In the applicability context of very compact coherent detection systems to the potentially wealthy market of THz detection, MASTHER aims at implementing a heterodyne receiver made from a sensitive lightweight cooled (80 K) hot electron bolometer (HEB) mixer chip with its solid state THz quantum cascade laser (QCL) source (at 60 K) as local oscillator in miniaturized cryocoolers.

The partners of the consortium are:

  • Unité mixte de physique CNRS - THALES (UMPhy / UMR 137).
  • Laboratoire des matériaux et phénomènes quantiques (MPQ / Université Paris Diderot Paris 7; UMR CNRS 7162).
  • Thales Research & Technology (TRT, Palaiseau).


The MASTHER project comprises 5 tasks:

  1. Coordination (GeePs)
  2. High temperature superconductor YBaCuO material growth and HEB physics (GeePs & CEA; UMPhy)
  3. Realization of YBaCuO HEB mixers and laboratory tests (GeePs)
  4. Realization of QCL THz sources and tests (MPQ)
  5. Integration and MASTHER prototype demonstration (TRT, GeePs & MPQ)
