Abstract

Various applications in astronomy and security need highly sensitive heterodyne receiver with a quantum cascade laser or a gas laser as local oscillator and a quasioptically coupled hot-electron bolometer mixer. Here we report on the development and characterization of the receiver components for frequencies up to 2.5 THz.
