Uniformly polarized GaAs laser array

Abstract

A structure is described which yields uniform polarization in the emitted light from an array of GaAs lasers. The exterior cleaved faces define a standard Fabry-Perot structure, and a 2-μ air space within the cavity inclined at the Brewster angle provides the necessary discrimination in gain between orthogonal modes to produce TE polarization (within ± 3°) for all lasers in the array. © 1972 The American Institute of Physics.
