Stabilized two-mode squeezed coherent state of light

We present a versatile method for producing two-mode stabilized squeezed coherent state (SSCS) of light with controllable nonclassicality. Our method involves seeding phase-coherent bichromatic fields into a nondegenerate optical parametric oscillator (OPO), where the global phase difference $\Phi$ between the bichromatic seed and pump fields plays a central role. When $\Phi=2n\pi$, where $n$ is an integer, we show that the two-mode SSCS has its nonclassical measure at its minimum possible value with an effective displacement that compensates for single-photon losses with injected photons. As a result, the SSCS has a larger mean photon number and controllable nonclassicality compared to an OPO without seed fields. We also show that near-perfect squeezing level can be obtained at that effective displacement without being subject to injection rates. We believe that the proposed quantum source of two-mode SSCS with controllable nonclassicality would be useful for continuous-variable photonic quantum information processing
