Abstract
Finite-element thermal modeling shows that thermoelectric cooled opera tion of IV-VI semiconductor diode lasers is possible by replacing the thermally resistive lead-salt substrate with copper. Contrasting therm al models reveal a 63 K decrease in active region temperature under no rmal operating conditions when PbTe is replaced with copper. This impr oved device structure can be obtained by using epitaxial-lift-off tech niques similar to those developed for III-V semiconductor devices.
