Abstract :
By incorporating a lumped-element impedance- matching network on the laser diode carrier/submount, the signal injection efficiency of electro-absorption modulator integrated lasers is significantly improved through the reduction of input return loss. Over a frequency range spanning from 5.8 to 10 GHz, an improvement of approximately 12% to 37% in signal injection efficiency is observed. To avoid increasing the component-count, a unique implementation of the lumped element impedance matching network is proposed.
