Parity-time symmetric optical cavities (Conference Presentation)

Paper Abstract

Optical cavities are imperative in micro/nanophotonics for their ability to provide resonance feedback and radiation enhancement. In recent years, the interplay between gain and loss using parity-time (PT) symmetry has opened up a new degree of freedom for cavity mode and emission control. I will first discuss a PT micro-ring cavity with the unique features of thresholdless PT symmetry breaking and single-mode lasing. Next, I will reveal a novel PT optical cavity which can support lasing and coherent perfect absorption modes within a single device and enable strong modulation from coherent amplification to coherent absorption.
