| 摘 要： | 最先利用非线性光学环路镜(NOLM)成功地将2.5Gbit/s的归零码光脉冲同时变换到不同的两个波长上.最大波长变换间距为35nm.实验系统中采用增益开关分布反馈半导体激光器(GS DFB-LD)产生的超短光脉冲作为控制光,采用分布反馈半导体激光器(DFB-LD)和波长可调激光器作为信号光.首次在1.55 μm波长段利用非线性光学环路镜进行波长变换过程时观测到了反相波长变换和脉冲畸变现象.

| Abstract: | Two-channel wavelength conversion for 2.5Gbit/s,return-to-zero optical Pulse based on nonlinear optical loop mirror was achived for the first time.The maximum separation between the control laser wavelength and the signal laser wavelength is 35nm.In this system,GS DFB-LD is used as the control pulse with the pulse width of 20ps,DFB-LD and wavelength tunable laser are used as signal lasers.The phase wavelength conversion and pusle degradation were observed for first time at the wavelength of 1.550μm. |
