Abstract
An integrated semiconductor optical amplifier-laser diode (SOA-LD) device includes a laser diode (LD) section fabricated on a substrate, a semiconductor optical amplifier (SOA) section fabricated on the substrate adjacent to the LD section; and a trench formed at least partially between the LD section and SOA section to electrically isolate the LD section and the SOA section while maintaining optical coupling between the LD section and the SOA section.
