Gamma-L scattering in InAs-based quantum cascade lasers studied using high hydrostatic pressure

Abstract

We show that by decreasing the lasing wavelength of InAs/AlSb-based quantum cascade lasers below 3mum, carrier leakage into the L-minimum of conduction band is responsible for their temperature sensitivity and limits their maximum operating temperature.
