Abstract :
We report on the development of a 4 channel, 10 Gbps/channel WDM laser transmitter module. The module includes four DFB MQW lasers operating in the 1550 nm fiber window. The small-signal characteristics of the DFB laser were measured from 50 MHz to 18 GHz, and a small-signal bias-dependent model was implemented using Libra software. This model was used with measured characteristics of the driver to analyze their interaction and predict the combined response. The drivers employ a commercially available HBT based monolithic amplifier. The electrical cross-talk of the drivers is presented. 10 Gbps waveforms are presented for the drive output and the optical signal.
