摘要
本文使用ＤＣ－ＰＢＨ半导体激光器（ＬＤ）芯片，研制了ＧＨｚ级“蝴蝶”型ＬＤ组件。组件包括ＬＤ芯片，ＬＤ背光监测ｐｉｎ光电二极管，半导体制冷器和一个热敏电阻。使用高频等效电路和散射（Ｓ）参数进行了ＬＤ组件的微波设计。测试了研制的组件微波阻抗和小信号高频特性。组件的电谐振频率为３．３４ＧＨｚ，光响应的３ｄＢ带宽大于１．５ＧＨｚ。其最高调制频率可达２．７ＧＨｚ。
Recently,the“butterfly”high speed laser diode(LD)module of the order of GHz has been developed.The LD module consists of a DC-PBH laser diode,a pin photodiode for monitoring the laser power,a thermoelectric cooler,and a thermis-ter.In designing the LD module,the high frequency equivalent circuits are employed and reported in this paper.The small signal high frequency characteristics of the module are measured,and the 3 dB bandwidth of electrical response of the module is more than 1.5 GHz,the modulation freqtiency is high up to 2.7 GHz.
