Demonstration of Efficient Nonreciprocity in a Microwave Optomechanical Circuit

Abstract

Nonreciprocal devices, in which electrical or optical signals travel in one direction only, are essential for telecommunication and quantum applications, but they are often both lossy and bulky to implement. A prototype device demonstrates nonreciprocity in a microwave optomechanical circuit that allows for dynamic isolation control while avoiding the need for large magnetic fields.
