本文从耦合腔理论出发分析了光纤光栅外腔半导体激光器的模式选择，得到了为达到稳定的高主边模抑制比所需的短外腔、短光纤光栅的器件设计原则.制作了两只光纤光栅外腔半导体激光器，Q1为短外腔(＜2mm)、短光纤光栅(4mm)结构，Q2为长外腔(20mm)、长光纤光栅(17mm)结构.测量Q1的主边模抑制比为35dB,Q2的主边模抑制比为10dB.

In this paper we analyze the mode selection of FGECSL using coupled cavity laser theory.In order to get stable high MSR output,short external cavity and short fiber grating should be used.We fabricated two FGECSLs,Q1 and Q2.Q1 is with short external cavity (＜2mm) and short fiber grating (4mm) and Q2 is with longer external cavity (about 20mm) and longer fiber grating (17mm).The MSR of these two lasers,are 35dB and 10dB respectively.
