Photoelastic effect from die bonding of diode lasers.
Abstract
The effect of strain induced from die bonding on the optical guiding of a ridge-waveguide laser is examined. Measurements of the strain in a p-down-mounted InP-based diode laser with fits to polarization-resolved photoluminescence are used to compute the resulting photoelastic effect in a ridge waveguide. The strain is found to alter the refractive indices in the material sufficiently in the waveguide to change the mode and reduce the optical …
