title: Simple Gaussian-beam model for GaAlAs double-heterostructure laser-diode-to-diffused-waveguide coupling calculations.
abstract: The GaAlAs laser-diode-to-diffused-waveguide edge-coupling efficiency has been evaluated using a Gaussian model for both the waveguide mode and the laser-output mode. The results of the calculation are shown to be in good agreement with previously unpublished coupling data.
