Polarization and isolation control for quantum cascade lasers in the mid-infrared

Abstract

There have been limited choices of optical materials in the Mid-Infrared for polarization control and subsequent isolation. We show several combinations of existing materials and optics that could realize polarization control and isolation for quantum cascade lasers in the MIR. Improvements in signal to noise ratio in MIR laser spectroscopy, as well as saturated absorption spectroscopy utilizing the isolation achieved, will be discussed.
