Abstract
The authors study surface-emitting 2nd harmonic generation as a powerful technique for the evaluation of birefringence in optical waveguides supporting several modes. This 1-shot diagnostic is demonstrated at 1319 nm in multilayer AlGaAs waveguides, before and after the lateral oxidn. of AlAs layers. [on SciFinder (R)]
