AlGaAs/GaAs short-cavity laser and its monolithic integration using microcleaved facets (MCF) process

Journal Article · · IEEE J. Quant. Electron.; (United States)

This paper describes the microcleaved facets process developed for AlGaAs/GaAs laser fabrication, which can avoid the previous substrate cleavage and therefore be applicable to preparing both discrete short cavity lasers and optoelectronic integrated circuits. An AlGaAs/GaAs double heterostructure ridge-waveguide laser with an extremely short cavity length, namely 20 microns, was first realized by this process. A threshold current as low as 20 mA and a single longitudinal mode lasing were achieved. The usefulness of this process for integrating a laser and a monitoring photodiode on a GaAs substrate is also demonstrated. 29 references.
