| contents | Squeezed light is a particularly useful quantum resource, which finds broad applications in quantum information processing, quantum metrology and sensing, and biological measurements. Here we show how to produce squeezed light exploiting the strong exciton-phonon nonlinear interaction in a semiconductor microcavity. The semiconductor microcavity is embedded with a quantum well, which supports both linear and nonlinear interactions among excitons, phonons, and cavity photons. We show that the strong exciton-phonon deformation potential interaction can induce a quadrature-squeezed cavity output field, and further reveal an important role of the exciton-photon coupling in engineering the squeezing spectrum and improving the robustness of the squeezing against thermal noise. Our results indicate that substantial optical squeezing in a broad band, up to tens of gigahertz, can be achieved using currently available parameters. |
