Nonlinear Delay Line Phase Shifters for Terahertz Superconductive Electronic Circuits.

Abstract

We report on the development of an electrically controllable superconducting phase shifter suitable for operation in a terahertz heterodyne receiver. The key physical principle of operation, and that of nonlinear kinetic inductance, is developed into a device theory and also appropriate design rules. Critical figures of merit are then identified and optimized designs presented. Experimental tests of prototypes are described that were used to help further refine the design rules. Although a practical phase shifter was not produced, the prospects for the device concept appear good. Terahertz, Phase-Shifter, Nonlinear, Kinetic Inductance, Superconducting.
