Optical Isolation using Compact Time-modulated Cavity Array

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

It is shown using coupled mode theory and verified using finite-difference time-domain simulations how a time-modulated three-cavity array can be designed to allow transmission from port 1 to port 2 but to prevent transmission from port 2 to port 1 thereby implementing optical isolation. The reciprocity of the system is broken by phase-shifting the modulation signal applied to each cavity by 120 degrees which gives the system a synthetic linear momentum.
