Enantiomer-discriminating sensing using optical cavities at exceptional points
M. Khanbekyan, Stefan Scheel
Abstract
We propose a method for the detection of the handedness of otherwise identical chiral molecules using the coupling to a high-$Q$ cavity at an exceptional point. In particular, we show that the rates of spontaneous emission for left- or right-handed enantiomers interacting with the cavity mode can be strongly enhanced or suppressed. This provides a strong spectroscopic signature to distinguish enantiomers. The enantioselectivity is shown to be robust against perturbations that move the cavity mode away from the exceptional point.
