Abstract :
Images of stress distributions in GaAs-based diode lasers have been obtained using scanned polarization-resolved photoluminescence. A stress resolution of about 107 dyn/cm2 and a spatial resolution of about 1 μm have been obtained. The experimental technique is described, and measured stress distributions due to ridge structures, metallization, applied force, and bonding are presented
