摘要:

提出并设计了一种高亮度、超紧凑的电泵浦GaAs基激光光源,利用腔内模式匹配参量下转换产生纠缠光子。为了描述高色散和耗散波导中的非线性混合,我们发展了一个非微扰量子理论的波导模式的参数下转换,考虑到模式色散,组和相位失配,传播,耗散和耦合到噪声水库的影响。我们将我们的理论扩展到量子化泵浦场的制度与一个新的方法的基础上的状态矢量的传播方程,解决了非微扰边值问题的参数衰减的量子化单光子泵浦模式,可以推广到包括耗散和噪声的影响。我们的形式主义是适用于各种各样的三波混频传播问题。它为解释实验结果和预测单片量子光子系统的性能提供了方便的解析表达式。

英文摘要:

We propose and design a high-brightness, ultra-compact electrically pumped GaSb-based laser source of entangled photons generated by mode-matched intracavity parametric down-conversion of lasing modes. To describe the nonlinear mixing in highly dispersive and dissipative waveguides, we develop a nonperturbative quantum theory of parametric down-conversion of waveguide modes which takes into account the effects of modal dispersion, group and phase mismatch, propagation, dissipation, and coupling to noisy reservoirs. We extend our theory to the regime of quantized pump fields with a new approach based on the propagation equation for the state vector which solves the nonperturbative boundary-value problem of the parametric decay of a quantized single-photon pump mode and can be generalized to include the effects of dissipation and noise. Our formalism is applicable to a wide variety of three-wave mixing propagation problems. It provides convenient analytic expressions for interpreting experimental results and predicting the performance of monolithic quantum photonic systems.
