Quality improvement of the dual-wavelength signals in DLOB via power equalization

Optoelectronics Letters 2008年第5期4卷 361-364页

作者： tian chang-yong wu chong-qing sun guang-na li xue li zheng-yong Key Lab. on Luminescence and Optical Information Technology of Education Ministry and Institute of Optical Information Beijing diaotong University Beijing 100044 China.

The data packet buffeting can be implemented in dual loop optical buffer （DLOB） through cross-phase modulation （XPM） between the control signal and the data packets. However, the output equality of dual wavelength signals will degrade due to the unbalanced gain and phase shift. This problem can be resolved by power oqualizafion using the saturation characteristics of SOA. The data packets with 2.5 Gb/s can be buffered in DLOB for 16 cycles corresponding to 16.5 μ*** extinction ratio of the output packet is 8 dB while the S/N is 8.1 dB.

信号在双环全光缓存器中进行缓存,是利用信号光和控制光在SOA中进行交叉相位调制来实现的。而对两个波长信号同时进行缓存将存在相位和增益不均衡问题,从而影响了输出信号的质量。本文提出了一种利用SOA的饱和特性对双波长信号进行功率均衡,而后写入缓存器的方法,使不同峰值功率信号获得相同的增益和相位调制,从而改善输出信号的质量。实验得到了速率为2.5Gb/s的NRZ码数据包缓存16圈的结果,信号缓存时间达到16.5με。输出信号的消光比为8dB,信噪比8.1dB.
