Bichromatic four-wave mixing and quadrature-squeezing from biexcitons in atomically thin semiconductor microcavities

Nonlinear optical effects such as four-wave mixing and generation of squeezed light are ubiquitous in devices sources. For new operating at low power, the resonant nonlinearity arising from two-photon sensitive bound biexciton a semiconductor microcavity is an interesting prospective platform. Due to particularly strong Coulomb interaction atomically thin semiconductors, these materials have strongly biexcitons operate visible frequency range electromagnetic spectrum. To remove pump laser generated or simultaneously excite nondegenerate polaritons, bichromatic-pump configuration with two spectrally separated lasers desirable. In this paper, we theoretically investigate spontaneous quadrature-squeezing bichromatically pumped microcavity. We explore different configurations that support degenerate scattering polaritons into biexcitons, respectively. find lead single- two-mode quadrature-squeezed light.
