Abstract

Laterally coupled diode lasers emitting at 1.3 um are presented. Devices were fabricated with distances between ridges varying from 2.76 um to 8.32 um. Electronic coupling effects are investigated by individually varying the currents in each ridge while monitoring output power. It is observed that for devices with 8.32 um separation between ridges there is minimal current sharing, whereas for 2.76 um separation there is considerable current sharing. Optical coupling is measured via the far-field, where most devices show out-of-phase locking, although in-phase locking is observed in a minority of cases. Devices therefore show conditions necessary for the observation of high speed dynamics.
