Aluminium free InGaAs/GaAs/InGaAsP/InGaP GRINSCH SL-SQW lasers at 0.98 μm

Abstract

Using InGaAsP lattice matched to GaAs, InGaAs/GaAs/InGaAsP/InGaP 0.98 μm GRINSCH SL-SQW lasers were fabricated for the first time. A high characteristic temperature of 215 K was measured at 10–70°C. A CW light output power of over 300 mW was achieved on 3 μm-wide ridge waveguide lasers with current-blocked regions near cavity facets.
