In 1993 fiscal year, the head investigator started this study during stay at Princeton Plasma Physics laboratory in Princeton University (PPPL), USA.Applicability and potential of the the Nonlinear Lortentz Computational Model (NLCM) have been studeid and extended toinclude another effects.1. The dark soliton is an NRZ optical pulse, contrary to the bright soliton which is the forerunner candidate of the soliton commnucation and is a RZ optical pulse. As a natural development of the traditional optical NRZ communication technique, the application of the dark soliton to the fiber transmitting is simulated by using the NLCM.The head investigator has reported the preliminary results in the oral session of the Japanese Society of Elctronics, Information, and Communucation. The title is "Computer Simulation of the Ultrashort Dark Soliton by the NLCM method (C-195)".2. The potentiality and the limit are presumed to be 10 Tbit/s by the computer simulation using the NLCM method. The abstract of the result is submitted to the Optics Letters. The title is "Potential capability of the dark soliton communication system".3. The simulation model is extended to the quasi 2-dimensional model. In this new model, two one-dimensional codes are synchronously run and the boundary condisions are solved as the simultaneous equation.4. The Y-splitting optical circuits are simulated by useing the quasi 2-dimensional model. By combining the pi/2 phase shifter with the quasi 2-dimensional model, the action of the optical switching hase been simulated.5. The effects of the stimulated Raman scattering has been incorporated to the NLCM,assuming that the ion is movile by the electromagnetic wave. The simplest model is adopted, but the Stokes scattering wave has been observed in the simulation.

1993财政年度，首席研究员在美国普林斯顿大学普林斯顿等离子体物理实验室期间开始了这项研究。研究了非线性洛坦兹计算模型(NLCM)的适用性和潜力，并将其扩展到包括另一种效应。暗孤子是NRZ光脉冲，而亮孤子是孤子通信的先导候选者，是RZ光脉冲。作为传统光NRZ通信技术的自然发展，利用NLCM模拟了暗孤子在光纤传输中的应用。主要研究人员在日本电子、信息和通信学会的口头会议上报告了初步结果。题目是《用NLCM方法(C-195)对超短暗孤子进行计算机模拟》。用NLCM方法进行计算机模拟，推定其潜力和极限为10TBit/S。研究结果的摘要已提交给《光学通讯》。题目是《暗孤子通信系统的潜在能力》。将仿真模型推广到准二维模型。在该模型中，两个一维码同时运行，边界条件作为联立方程求解。利用准二维模型对Y分裂光路进行了模拟。将pi/2移相器与准二维模型相结合，对光开关的作用进行了模拟。将受激拉曼散射的影响引入到NLCM中，假定离子是通过电磁波运动的。采用最简单的模型，但在模拟中观察到了斯托克斯散射波。
