AlGaAs/GaAs microcleaved facet (MCF) laser monolithically integrated with photodiode

Abstract

A new AlGaAs/GaAs double-heterostructure laser with microcleaved facets, restricted just at stripe contact edges, has been developed. This laser and a junction photodiode have been monolithically integrated in a single GaAs substrate. Low-threshold current lasing and high-fidelity monitoring characteristics have been demonstrated.
