论文摘要
多模综合干涉仪对于光谱工程和计量应用都有很大的潜力。但是，集成平台的材料分散构成了限制此类干涉仪的性能和精度的障碍。同时，当在一定频率范围内的测量值时，两色非线性干涉仪为计量应用提供了重要的工具。在此手稿中，我们从理论上开发和研究了以超敏感模式运行的集成的多模su（1,1）干涉仪。通过确保对集成平台的正确设计，我们抑制了分散体，从而大大提高了干扰模式的可见性。我们证明，这种干涉仪克服了广泛参数增益范围的经典相位灵敏度极限，当生成$ 3*10^4 $光子时。
Multimode integrated interferometers have great potential for both spectral engineering and metrological applications. However, material dispersion of integrated platforms constitutes an obstacle which limits the performance and precision of such interferometers. At the same time, two-colour non-linear interferometers present an important tool for metrological applications, when measurements in a certain frequency range are difficult. In this manuscript, we theoretically develop and investigate an integrated multimode two-colour SU(1,1) interferometer that operates in a supersensitive mode. By ensuring a proper design of the integrated platform, we suppress dispersion and thereby significantly increase the visibility of the interference pattern. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to $3*10^4$ photons are generated.
