Waveguide-integrated THz Quantum-Cascade Lasers for Atmospheric-Research Satellite Payloads

Abstract

Terahertz-frequency quantum-cascade lasers (THz QCLs) are compact, electrically-driven sources of narrowband radiation in the ~2–5 THz band. Numerous scientifically important gas-phase species within the Earth’s upper atmosphere have distinctive spectral features within this band, making QCLs attractive sources for spectroscopic and radiometric atmospheric studies. In this paper, we demonstrate the integration of a QCL with a satellite-compliant cryocooler, precision-micromachined wave-guide, a pair of diagonal feedhorns and a Cassegrain telescope, as key steps toward a complete 3.5 THz integrated receiver system.
