实用化宽带半导体激光器组件的研制及其特性的研究

Make of the Practicable Broadband Laser Diode Module and Studies on its Characteristics

使用ＤＣ－ＰＢＨ型激光二极管芯片，设计制作了实用化封装形式的宽带半导体激光器组件，在理论上和实验上研究了组件的封装模型、小信号频率调制特性和非线性失真，其光响应为３ｄＢ，带宽大于２ＧＨｚ．该器件可满足六次群光通信系统的带宽要求，也可用于ＧＨｚ级微波副载波光通信系统．

Using DC-PBH laser diode(LD), the broadband LD module of practicable package type is developed. The LD module is studied and measured on the packaged LD model, involving small signal modulation characteristics and nonlinear distortion. Its 3 dB bandwidth of optical resonance is more than 2GHz. This device is able to satisfy the bandwidth need of 2. 488 Gb/s in the optical fiber communication system and be used in the GHz microwave subcarrier multiplex optical fiber communication system.
