Lasing-induced reduction in core heating in high wall plug efficiency quantum cascade lasers
Anthony J. Hoffman, Phillip X. Braun, Matthew D. Escarra, Scott S. Howard, Kale J. Franz et al.
Quantum cascade (QC) laser core heating is a primary impediment to high device wall plug efficiency (WPE). Here, we demonstrate that efficient photon generation produces a quantifiable reduction in heating of the QC laser core temperature. By superimposing low duty cycle current pulses on a core-hea ...
