摘要
在高速光电子器件的微波封装过程中,需要综合考虑封装寄生参数和芯片寄生参数对器件高频性能的影响。利用封装寄生参数对芯片寄生参数的补偿作用,成功实现了10 Gb/s电吸收调制激光器(EML)的高频封装。通过封装前后芯片和器件的小信号频率响应测试结果对比,器件的反射参数和传输参数有所改善,3 dB带宽达到10 GHz;并进行了10 Gb/s速率的光纤传输实验,经过40 km光纤传输后通道代价不到1 dBm(误码率为10-12),满足10 Gb/s长距离光纤传输系统的要求。
Abstract
A novel microwave packaging technique for 10 Gb/s electro-absorption modulator integrated with distributed feedback laser (EML) is presented. The packaging parasitic and intrinsic parasitic are both well considered, and the packaging circuit is synthetically designed to compensate the intrinsic parasitic of the chip. A butterfly packaged EML module has been successfully developed to approve that. The small-signal modulation bandwidth of the butterfly-packaged module is about 10 GHz. Optical fiber transmission experiments at a data rate of 10 Gb/s show that the module can be used for long-haul transmission. After transmission through 40 km, the power penalty is less than 1 dBm at a bit-error-rate of 10-12.
