Design of Silicon-Based Quantum Squeezer

Abstract

We introduce a silicon squeezer designed for high levels of squeezing and compatibility with state-of-the-art integrated balanced detection systems. Our approach combines linear elements, such as dispersion control and cavity design, with the strategic selection of pump parameters to enhance nonlinear performance. To optimize signal confinement and reduce phase mismatches in four-wave mixing (FWM), we meticulously adjust the waveguide dimensions, cladding materials, bend radii, and directional coupler settings. This comprehensive strategy is aimed at minimizing FWM discrepancies and ensuring effective signal confinement, demonstrating our commitment to addressing the complexities of high-performance squeezing in silicon platforms.
