Paper Abstract

Room temperature CW operation of quantum cascade lasers has recently been demonstrated. However, this important performance milestone still remains a technological challenge. QCLs are characterized by high electrical power consumption (3 - 5 W) and low wall plug efficiencies (1 - 4%). This leads to considerable self-heating that can block CW operation. In order to overcome this self-heating device fabrication has to be optimized for high thermal extraction. In this paper we will demonstrate the factors that influence CW operation in quantum cascade lasers (QCLs). We will compare the performance of different device processing design to achieve maximum thermal dissipation and reduced power consumption.
