This work focuses on improving the performance of laser diodes, an important component of any optical communication system in data centers. The focus is to demonstrate laser diodes with high modulation bandwidth, small footprint, and low power consumption.

The distributed feedback laser diode is the laser of choice in our work to demonstrate lasers for different purposes. It is also the preferred optical source in optical communication due to its stable single-mode behavior, and high side-mode suppression ratio. The lasers demonstrated throughout this work are: (1) self-pulsating lasers, (2) bandwidth enhanced lasers, (3) low-threshold lasers, (4) electro-absorption modulated lasers, and (5) compact lasers.
