Abstract

Variation of lasing wavelength with temperature is a key factor to determine packaging thermal resistance in laser diodes. Using proprietary mounting technology that clamps laser bars instead of using soldering material we can precisely control the stress applied on the laser bars. We experimentally demonstrate that uniaxial stress in the normal direction of the p-n junction (which results in tensile stress in the lattice) increases the temperature characteristic of laser diodes. We report a temperature characteristic raise between 10% and 50% under different stress conditions.
