摘　　要：利用一个一端镀有增透膜的Ｆ－Ｐ腔半导体激光器芯片和一段反射率为５０％的光纤光栅组合成一混合腔激光器，腔长约为２ｃｍ。在５０ｍＡ的偏置电流下，主边模抑制比为３７．６ｄＢ，出纤功率为１ｍＷ。A hybrid semiconductor laser is fabricated by combining an anti reflection coated F P laser chip with an in fiber Bragg grating (FBG). The cavity length is about 3 cm and the peak reflection of the FBG is 50%. At a bias of 50 mA, the output is 1 mW with a side mode suppression ration of 37.6 dB. A simple theoretical analysis is also given.
