Temperature Modulation Technique Applied to GaAs Lasers

Temperature is a key factor in determining the output stability of lasers. The performance of lasers tends to deteriorate with increasing temperature: the laser threshold increases while the efficiency decreases. In the current work, the temperature dependence of laser output power as a function of temperature and bias current is studied. Standard 850 nm and GaAs lasers with AlGaAs claddings and custom thermoelectric cooler modules are used to demonstrate the desired measurements.unpublishednot peer reviewedU of I OnlyUndergraduate senior thesis not recommended for open acces
