Backward Cherenkov radiation emitted by polariton solitons in a microcavity wire
Abstract
Cherenkov radiation is generated from fast electrons and its optical analogue plays an important role in many nonlinear optical effects. Here, Skryabin et al. demonstrate backward-propagating photonic Cherenkov radiation generated from solitons in a semiconductor exciton-polariton system.
