We investigate surface-emitting second harmonic generation as a powerful technique for the evaluation of birefringence in optical waveguides supporting several modes. This one-shot diagnostic is demonstrated at 1319 nm in multilayer AlGaAs waveguides, before and after the lateral oxidation of AlAs layers.

Abstract

We investigate surface-emitting second harmonic generation as a powerful technique for the evaluation of birefringence in optical waveguides supporting several modes. This one-shot diagnostic is demonstrated at 1319 nm in multilayer AlGaAs waveguides, before and after the lateral oxidation of AlAs layers.
