Dipolar polaritons squeezed at unitarity
Abstract
Interaction of dipolar polaritons can be efficiently tuned by means of a shape resonance in their excitonic component. Provided the resonance width is large, a squeezed population of strongly interacting polaritons may persist on the repulsive side of the resonance. We derive an analytical expression for the polariton coupling constant, and we estimate the degree of squeezing of the emitted light. The squeezing may approach 100 % in typical experimental conditions. Our arguments hold promises for implementation of strong correlations in quantum photonics.
