Control of spontaneous emission dynamics in microcavities with chiral exceptional surfaces
Q. Zhong, A. Hashemi, Ş. K. Özdemir, R. El-Ganainy · Physical Review Research · 2021
The authors show how chiral exceptional surfaces can be used to tune the spontaneous emission rate from a single quantum emitter inside an optical microcavity, from total suppression to a two fold enhancement compared to a similar cavity operating at a diabolic point.
