Temperature-dependent Gain and Loss in High Performance Quantum Cascade Lasers at 8.2 and 10.3µm

Not Accessible

Your library or personal account may give you access

Abstract

Temperature-dependent optical gain and waveguide loss were measured for Quantum Cascade lasers with wavelengths of ~8.2 and ~10.3µm. The nature of the temperature dependence of the loss indicates an extra mechanism of resonant intersubband absorption.
