Abstract :
An active multimode interferometer (MMI) laser diode (LD) concept is presented. It has been verified via a 1.48 μm high power application. The active MMI-LDs, having a larger pumping area compared to that of regular single-stripe LDs with the same length, showed no significant degradation in slope efficiency and up to 50 mW power improvement resulting in 170 mW saturated output power
