Quantum Limits of Superconducting Heterodyne Receivers.

Abstract

The goal of this research is to produce quantum limited SIS quasiparticle heterodyne receivers at submillimeter wavelengths. The approach is to compare the performance of waveguide and planar lithographed quasi-optical SIS mixers in W-band (lambda approx. 3mm) in order to understand the factors which upgrade the performance of the latter. This information will be used to optimize the planar quasi-optical mixers. Finally, these optimized designs will be scaled to submillimeter wavelengths. Systematic tests of both types of mixers have been carried out during the second grant year. Improved designs of planar quasi-optical mixers gave been designed and fabricated. The construction of test apparatus for submillimeter wavelengths has begun.
