• パワーレーザーの新パラダイム創成を目指した時空間分割受動コヒーレント結合法の確立
  桐山 博光; 戸田 裕之; 宮坂 泰弘; 鈴木 将之
  コヒーレント光であるレーザーの最大の特徴は、パワースケーリングは原理上無限にできることである。光を電界位相まで揃えたコヒーレント結合ができるため、独立の増幅器から出たレーザーを結合できるからである。2018年ノーベル物理学賞を受賞したチャープパルス増幅（CPA）法で可能となったペタワット(PW=10の15乗W)よりも3桁高いエキサワット(EW=10の18乗W)レーザーを実現できる基盤技術を確立するため、ハイパワーレーザーのコヒーレント結合技術を開発する。最も困難な課題は空間波面の整合性であり、時間領域の周波数や位相をいくら整合させても結合はうまくいかない。本研究では、技術的に未開拓な独立の固体レーザー増幅器から出た全てのレーザーが全て同じ光路を伝搬することで受動的に波面が一致する新たなアイデアに挑む。 今年度は、マイケルソン干渉計及びサニャック型干渉計を応用したビームの時間分割・結合器の試作・試験を行い、受動コヒーレント結合効率を分光器によりスペクトル強度・形状とともに評価した。並行して、理論限界の結合効率を得るために、自作の光線追跡コードや3次元波面解析コードによるビーム伝搬特性の数値解析を実施し、実験結果と比較して、実験パラメータにフィードバックした。これらによりフェムト秒極短パルスを制御することなく、位相ずれゼロで受動結合（自動空間波面整合）できる調整手法を確立し、理論限界（位相ずれゼロ）の結合効率を達成した。, 日本学術振興会, 科学研究費助成事業, 2021/07 -2025/03, 挑戦的研究(開拓), 国立研究開発法人量子科学技術研究開発機構

• An optical clock multiplier with phase stabilized between adjacent optical pulses
  Toda Hiroyuki; TAKAMA Renjo; OTSUKI Masato; SUGIYAMA Kiyotaka; BUECHLER Pierre
  We demonstrate a phase stabilized quadruple OTDM multiplier for RZ/CS-RZ optical clock with optical couplers. An optical bandpass filter (OBPF) was used to filter the desired sidebands from the multiplier output, and the filtered output was used for the stabilization. 10 GHz optical clock was multiplied to 40 GHz with 17 dB undesired sideband suppression ratio. We made a numerical simulation of octuple OTDM multiplier for RZ/CS-RZ optical clock. It turned out that very steep OBPF characteristic was required for filtering the desired sidebands, and which conclude that realization of 16 times OTDM multiplier with one OBPF for phase stabilization is difficult. We made a phase stabilized 2 x OTDM multiplier with polarization maintaining optical fiber. 10 GHz optical clock was multiplied to 20 GHz with undesired sideband suppression ratio of > 25 dB and > 22 dB for RZ and CS-RZ optical clock, respectively., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2012/04 -2016/03, Principal investigator, Competitive research funding, Grant-in-Aid for Scientific Research (C), Doshisha University

• Ultrahigh-speed optical transmission and signal processing utilizing nonlinear effects in fibers
  MATSUMOTO Masayuki; TODA Hiroyuki; MARUTA Akihiro; KAWASAKI Zenichiro
  1. Achievements relating to ultrahigh-speed long-distance transmission utilizing fiber nonlinearities are as follows : (1) We have demonstrated transmission of a pair of soliton pulses with separation of 12.5ps, corresponding to a bit rate of 80Gb/s, over more than 7,000km in a densely dispersion-managed (DDM) recirculating fiber loop. (2) We have experimentally demonstrated the existence of bi-solitons, with which pulse-to-pulse interaction is eliminated, by a recirculating transmission experiment. We also examine stability of bi-solitons against variations in initial pulse parameters and applicability of bi-solitons in WDM transmission. (3) By numerical simulations we have shown that high spectral-efficiency soliton transmission can be obtained by a combined use of doubly-periodic dispersion management and soliton transmission control. We have also shown that DDM soliton transmission with filter control realizes distance more than 5,000km at 160Gb/s but with limited effectiveness of dispersion compensation at the receiver end. 2. Achievements relating to optical signal processing utilizing fiber nonlinearities are as follows : (1) We have carried out quasi-80Gb/s recirculating transmission experiment and have shown that error-free transmission distance can be extended from 300 to 1,000km by the use of an all-optical 2R regenerator based on self-phase modulation in a fiber. (2) We have shown through a 10Gb/s transmission experiment that an all-optical limiter based on saturation of four-wave mixing in a fiber improves BER of DPSK transmission through suppression of nonlinear phase noise. (3) We have proposed signal power to pulse number conversion based on slicing of SPM-broadened spectrum by an arrayed waveguide grating and have demonstrated all-optical two-bit AD conversion. We have also proposed and demonstrated optical DA conversion using cascaded optical switches. (4) We have proposed and demonstrated all-optical variable delay method using temporal shifts produced by collisions between solitons with different wavelengths., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2001 -2005, Grant-in-Aid for Scientific Research (S), Osaka University
• Research on photonic IP routing
  KITAYAMA Ken-ichi; MARUTA Akihiro; TODA Hiroyuki; MATSUMOTO Masayuki
  In this research a new optical packet switching architecture is proposed and investigated. Output line contention is resolved by optical delay line buffers. By introducing a WDM technology, parallel buffer can be equipped with multiple wavelengths on the optical delay line buffer. An ultrafast optical code label processing technique would be fast enough for packet scheduling that selects the appropriate output port, wavelength, and delay line buffer. To evaluate the switch performance, we model an output port of our switch as a multi-server and multi-queue system where each server corresponds to a wavelength and where each arriving packet joins the shortest queue. The results of the analysis and of simulation experiments show that the use of the WDM technique can greatly improve the switch performance in terms of packet loss probabilities. The optical implementation of routing table lookup which allows to perform the long-prefix match is investigated. The WDM buffering using fiber delay lines is experimentally studied at 40Gb/s., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2000 -2002, Grant-in-Aid for Scientific Research (B), Osaka University
• Research on nonlinear optics and lutra high-speed fiber-optic transmission based on the theory of integrable systems
  MATSUMOTO Masayuki; MARUTA Akihiro; TODA Hiroyuki
  1.Theoretical analysis of dispersion managed solitons (a)We found that initial difference in amplitude and/or phase between neighboring dispersion managed(DM)soliton lses is effective to reduce the pulse-to-pulse interaction. (b)We discovered symmetric bi-soliton solution in DM fiber which showed extremely low pulse-to-pulse interaction. 2.Transmission control of dispersion managed solitons (a)The energy of DM soliton is stabilized by inserting optical devices in transmission fiber such as optical bandpass filter and/or intensity modulator synchronously driven with the transmitting solitons. We found that the effectiveness strongly depended on the inserting position of the devices. Moreover, the pulse energy can be stabilized without optical bundpass filter if the position of the intensity modulator is properly chosen. (b)We found that the influence of channel-to-channel interaction on WDM soliton transmission can be greatly reduced by bit by bit tuning of the decision time of the receiver. (c)We proposed dense DM solitons where the period of the dispersion management is much shorter than the EDFA spacing for ultra-high speed(>80 Gbit/s)transmission. Dispersion slope compensation can be effectively done by inserting dispersion shifted fiber for the compensation right before EDFA's. 3.Ultra short optical pulse generation and soliton transmission exeriment (a)We proposed the use of comb-like dispersion profiled fiber(CDPF)constructed by standard single mode fiber and dispersion shifted fiber for soliton transmission. The bit error rate of < 10-9 was achieved in 10 Gbit/s, 2,000 km transmission experiment in a recirculating loop, where the EDFA spacing of 80 km is twice as long as the dispersion distance. (b)We made 40 Gbit/s dense DM soliton transmission experiment with 60-km long dense DM fiber constructed by non-ro dispersion shifted fiber and observed eye pattern after 1,630 km transmission. (c)1.6ps. 160 GHz optical soliton pulses were generated by CDPF and optical pulse compression. (d)We transmitted two 3.7-ps width optical pulses with 10 ps separation in dense DM fiber and observed that the pulse separation became shorter after transmission. 2.6 ps, 87 GHz dense DM solitons were transmitted over 600 km. 4.Nonlinear optical device (a)We analyzed the switching characteristics of nonlinear optical loop mirror(NOLM)where dispersion configuration of the loop is asymmetric. Both extinction ratio and switching threshold can be better than that of the conventional NOLM. (b)We analyzed timing and energy jitters included in the output optical pulses from actively mode-locked dispersion-managed fiber ring laser. Both jitters can be greatly reduced by properly choosing the position of the intensity modulator and the optical bandpass filter. (c)We proposed a new optical RZ receiver using pulse reshaping characteristics of nonlinear optical pulse propagating along normal dispersion fiber. We demonstrated that the amplitude and phase margins were greatly improved in 10 Gbit/s, 12,000 km optical soliton transmission., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1997 -2000, Grant-in-Aid for Scientific Research (A)., Osaka University
• Optical soliton communication-Application to the long distance and high data-bit communication-
  HASEGAWA Akira; MARUTA Akihiro; TODA Hiroyuki; MATSUMOTO Masayuki; ANDREKSON Peter A; KODAMA Yuji
  We obtained theoretically a new soliton (the quast-soliton) having a much better transmission properties than an ideal soliton. The quasi-soliton can be produced by means of a proper dispersion mapping. The quasi-soliton allows much smaller pulse spacings than an soliton thus it can increase bitrate per a wavelength channel. In addition its stationary pulse shape is much more suited for OTDM networks than the so called dispersion managed solitons. Properties of dispersion managed soliton in a fiber having periodic variation of dispersion were theoretically studied in its application for wavelength multiplexing as a function of the difference of the dispersion, DELTAD.The frequency shift was found to decrease and disappear periodically as a function of DELTAD. Experiments of transmission of 2x10Gbps WDM solitons were performed with sliding filter control and confirmed the transmission property depends on the wavelength characteristics of EDFA.With collaboration of Prof.Andreckson of Chalmer's University, it was demonstrated that the decrease of S/N ratio of the light source deteriorate the transmission property of a soliton. We succeeded transmission of 10Gbps solitons over 16,000km with bit error rate of less than 10^<-9>. In addition, we could transmit 10Gbps solitons having amplifier spacing of 80 kms over a distance of 2,000km by means of comb type dispersion management. With collaboration of Dr. Chernikov at lmperial College, we could succeed generation of near Fourier transform limited soliton pulse having autocorrelation width of 3.7ps and repetition rate of 86.8Ghz with the use of the induced modulational instability, an invention of Prof.Hasegawa., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1995 -1997, Grant-in-Aid for international Scientific Research, Osaka university

  Future ultra-high-speed optical transmission network systems require flexibility of time division and wavelength division multiplexing. Optical solitons are most suitable for such systems. Research on optical soliton based ultra-high speed communication systems have been performed both in theory and in experiments. Particular emphases are placed on soliton control and dispersion management in order to achieve wavelength multiplexing both of which are our original contributions. In experiments, we have demonstrated a stable ten Gigabit/second optical soliton transmission over tramspacific distance using guiding filter and frequency sliding in recirculating fiber loop. In addition preliminary experiments of two ten Gigabit/second wavelength division multiplexing were performed. In theory, we have shown for the first time that for the successful transmission of wavelength division multiplexed solitons in fibers with repeated amplifications, a dispersion decreasing fiber is most effective. This idea was demonstrated in a experiment at Bell Laboratories of 8 times 10 Gigabit/second transmission over 9,000 Kilometers. Similar experiments are being planned also by our group. In addition to these results, we have studied various methods of soliton control and of coding information on soliton parameters. The results were published shown in the list of publications., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 1992 -1995, Grant-in-Aid for Specially Promoted Research, Osaka University
