Abstract
A vertical cavity surface emitting laser is formed by eutectically bonding a laser cavity, defined by an active layer disposed between first and second, stacked mirror assemblies, to a host substrate which has a predetermined anisotropic coefficient of thermal expansion. During the forming process, a uniaxial strain is induced within the laser cavity. With this arrangement, large arrays of vertical cavity surface emitting lasers can be formed with predetermined polarization states that are based on the selected anisotropic host substrate.
