Abstract
Angular scanning of the far‐field intensity peak of a GaAs/GaAlAs DH injection laser is demonstrated. This scan is accomplished by adjusting the current levels between two closely space stripe contacts, thereby creating an asymmetric gain/refractive index profile through which the laser beam propagates. Thus, this effect is somewhat analogous to passing the laser beam through a wedge. A deflection of the peak laser beam intensity of ±14° along the p‐n junction plane is observed.Keywords
