Abstract
Double‐heterostructure GaAs–Al x Ga1−x As injection lasers which operate continuously at heat‐sink temperatures as high as 311°K have been fabricated by liquid‐phase epitaxy. Thresh‐olds for square diodes as low as 100 A/cm2 and for Fabry‐Perot diodes as low as 1600 A/cm2 have been obtained. Some details of preparation and properties are given.Keywords
