论文摘要
用正交平方的形式的电磁量子波动的修改是一种中央量子资源，可以通过非线性光学过程产生。在原子薄的半导体中，强烈结合的biexciton的连贯的两光子激发促进了这样的过程。从理论上讲，将原子上薄的半导体与光腔连接起来，可以利用这种两光子的共鸣，并利用Biexcitonic参数增益来产生挤压光线，并输入能力以低于当前的巨大设备，低于当前的巨大设备，并依靠依赖于远非线的非线性非线性的非线性非线性材料。此外，发现挤压带宽在几个MEV范围内。这些结果将原子薄的半导体确定为片上挤压光源的有前途的候选者。
Modification of electromagnetic quantum fluctuations in the form of quadrature-squeezing is a central quantum resource, which can be generated from nonlinear optical processes. Such a process is facilitated by coherent two-photon excitation of the strongly bound biexciton in atomically thin semiconductors. We show theoretically that interfacing an atomically thin semiconductor with an optical cavity allows to harness this two-photon resonance and use the biexcitonic parametric gain to generate squeezed light with input power an order of magnitude below current state-of-the-art devices with conventional third-order nonlinear materials that rely on far off-resonant nonlinearities. Furthermore, the squeezing bandwidth is found to be in the range of several meV. These results identify atomically thin semiconductors as a promising candidate for on-chip squeezed-light sources.
