A Compact Topological Microwave Isolator

Alexander Cerjan

Research output: Contribution to journal › Comment/debate

Abstract

A central goal of topological photonics has been to develop compact isolators using protected, non-reciprocal edge states. A recent demonstration of a ferrite-based microwave isolator leverages the magnon-induced topological photonic bandgap to achieve over 100 dB of isolation in a device smaller than a single free-space wavelength.
