本文从理论上研究了基于半导体光放大器（SOA）的双环路光缓存器（DLOB）中双波长分组信号的存储。DLOB的调制功能是通过SOA引起的交叉相位调制来实现的。研究了双波长光脉冲存储时，非线性相移对包脉冲啁啾和失真的影响。研究发现，当双波长脉冲的重叠面积小于脉冲宽度的一半时，输出脉冲在存储后的畸变可以忽略不计。而当双波长脉冲完全重叠时，畸变最严重。输出包脉冲的峰值功率降低了约30%。所得到的结果可以为实验实施提供有益的见解。
In this paper, we theoretically investigate the dual-wavelength packet signal storage in the semiconductor optical amplifier (SOA)-based dual-loop optical buffer (DLOB). The loadable function of the DLOB is implemented by the cross phase modulation induced by the SOA. The influence of the nonlinear phase shift on the chirp and distortion of the stored packet pulse is examined for the case of the dual-wavelength loadable operation. It is found that, when the overlapping area of the stored dual-wavelength pulse is less than half of the pulse width, the distortion of output pulse after storage is negligibly small. However the most severe distortion appears when the dual-wavelength pulses overlap completely. The peak power of output packet pulse is reduced by approximately 30%. The obtained results can provide helpful insight for experimental implementation.
