1. Establishment of all-opticallogic gate devices: On the semiconductor-optical-amplifier-integrated Mach-Zehnder interferomator all-optical gates (SOA-MZI), we have reduced propagation loss significantly by improving fabrication techniques of high-mesa waveguides and by introducing low dope cladding layers. Then, concerning the all-optical logic gate device based on active multimode couplers (MMIs), we have developed a new model and a simulation tool to analyze cross phase modulation between optical pulses.2. Establishment of all-optical flip-flops: Regarding the all-optical flip-flop of MMI bistable laser diode (BLD) type, for the sake of obtaining single-longitudinal mode operation and cascadability, we fabricated devices incorporating distributed Bragg reflectors (DBRs). As a result, we could achieve complete single longitudinal mode oscillation with a 23dB side-mode suppression ratio as well as a broad operation wavelength range of 1520-1570nm and a high switching extinction ratio … More of 26dB. Dynamic characterization with 10ns input optical pulses revealed good performances, such as 16dB dynamic extinction ratio, 320ps rise time, 470ps fall time, and a dynamic operation wavelength range of 1540-1570nm. Furthermore, the introduction of a tensile strained quantum well active layer resulted in a 16dB extinction all-optical flip-flop operation which is completely independent of polarization.3. Analysis and design of a digital all-optical integrated circuit prototype: We constructed a fundamental all-optical packet processing circuit consisting of the all-optical logic gate and the all-optical flip-flop, and conducted wavelength-multiplexed packet routing demonstration by all-optical processing. Consequently, penalty-free all-optical switching with 320Gbps throughput (40Gbps X 8 lambda) has been realized.4. Integratable optical non-reciprocal devices: An optical waveguide isolator of non-reciprocal loss type that can be operated at high temperatures has been developed by utilizing ferromagnetic MnSb. Good characteristics including isolation ratio of 6.0dB/mm, insertion loss of 4.9dB/mm, and a temperature range of 20-100℃ have been demonstrated. Less

1.全光逻辑门器件的建立：在半导体-光放大集成马赫-曾德尔干涉器全光门(SOA-MZI)上，通过改进高台面光波导的制作工艺和引入低掺杂包层，显著降低了传输损耗。然后，针对基于有源多模耦合器的全光逻辑门器件，建立了分析光脉冲间交叉相位调制的新模型和仿真工具。全光触发器的建立：对于MMI双稳态激光二极管(BLD)型全光触发器，为了获得单纵模工作和级联，我们制作了带有分布布拉格反射器(DBR)的器件。结果表明，该激光器可以实现完全的单纵模振荡，边模抑制比为23dB，工作波长范围为1520-1570 nm，开关消光比…较高超过26分贝。在输入光脉冲为10 ns的情况下，获得了16db的动态消光比、320ps的上升时间和470ps的下降时间，动态工作波长范围为1540~1570 nm。此外，张拉应变量子阱有源层的引入导致了16db消光全光触发器的工作，完全与偏振无关。数字全光集成电路样机的分析与设计：构建了由全光逻辑门和全光触发器组成的基本全光分组处理电路，并通过全光处理进行了波分复用路由演示。从而实现了320Gbps吞吐量(40Gbps×8 nm)的无损耗全光交换。可集成光学非互易器件：利用铁磁性MnSb研制了一种可在高温下工作的非互易损耗型光波导隔离器。器件具有良好的特性，隔离度为6.0dB/mm，插入损耗为4.9db/mm，温度范围为20-100℃。较少
