A GaInAsP/AR GaInP laser diode is provided with an AlGaAs type II carrier blocking layer in the waveguide of the diode. The resulting diode exhibits a relatively low threshold current, an increased slope efficiency and characteristic T0 and T1, for the diodes are less limited by carrier leakage.

Un diodo del laser de GaInAsP/AR GaInP se proporciona un tipo portador de AlGaAs de II que bloquea capa en la guĂ­a de onda del diodo. El diodo que resulta exhibe una corriente relativamente baja del umbral, una eficacia creciente de la cuesta y un T0 caracterĂ­stico y T1, porque los diodos son limitados menos por salida del portador.
