Paper Abstract

The theoretical model considering nonlinear effects in the external cavity semiconductor laser with sampled fiber grating has been presented. Such effects are including the asymmetric side mode suppression ratio (SMSR) or power characteristics, and hysteresis phenomena. This theoretical model is based on the transmission line theory on compound cavity. The parameters of the laser, e.g. active section length and phase section length, have been optimized to suppress such nonlinear effects, which makes the device control simple and reliable, while the performances such as 16nm tuning range, 40dB SMSR, 8.5mW output power can be maintained.
