摘要

众所周知,半导体光放大器(SOA)材料是一种理想的非线性材料,它不仅具有很高的非线性,而且信号增益也很高。使用增益饱和SOA作为非线性交互介质,还演示了20gb /s的全光波长转换和更高比特率的全光TDM解复用。在这项工作中,我们研究了使用SOA作为非线性交互元件的性能,用于所有光波长转换和π相移倍数的开关/解复用。我们还展示了基于类似原理的全光学NOR (NAND for负逻辑)门的想法。

Performance of all optical wavelength conversion, logic operation and switching using semiconductor optical amplifiers
It is well known that semiconductor optical amplifier (SOA) material is an ideal nonlinear material, which has not only a very high nonlinearity but also the signal gain. Using the gainsaturated SOA as a nonlinear interaction medium, all optical wavelength conversion at 20 Gb/s and all optical TDM demultiplexing at even higher bit rates have also been demonstrated. In this work we study the performance of using the SOA as an nonlinear interaction element for all optical wavelength conversion and switching/demultiplexing with a multiple of π phase-shift. We also demonstrate the idea of an all optical NOR (NAND for negative logic) gate based on a similar principle.
