Abstract
High-temperature performance of a beam-expander (BEX) integrated laser was dramatically improved by reducing the current leakage in both lon gitudinal and lateral directions. Proton implantation into the BEX reg ion and a reverse-mesa structure were combined to improve the high-tem perature characteristics, A threshold current of 23.1 mA at 85 degrees C and a very high-characteristic temperature T-0 (25 degrees C-85 deg rees C) of 74 K were achieved, Stable operation for over 3000 h under a 10-mW output power at 70 degrees C were confirmed.
