论文摘要
硅光子积分电路中的光子对产生依赖于三阶非线性混合。由于相位匹配的要求和组速度分散，该方法通常需要TE极化光。在这里，我们在线性未偶联的硅谐振器中演示了TM偏振光子对产生，其分散率比以前的工作多于数量级。我们达到的速率高于2.8 kHz，并提高了$ g^{（2）}（0）= 0.0442 \ pm 0.0042 $的预示二阶相关性。该方法可以在分散介质中进行相位匹配，并为硅光子设备中的新纠缠产生铺平了道路。
Photon pair generation in silicon photonic integrated circuits relies on four wave mixing via the third order nonlinearity. Due to phase matching requirements and group velocity dispersion, this method has typically required TE polarized light. Here, we demonstrate TM polarized photon pair production in linearly uncoupled silicon resonators with more than an order of magnitude more dispersion than previous work. We achieve measured rates above 2.8 kHz and a heralded second order correlation of $g^{(2)}(0) = 0.0442 \pm 0.0042$. This method enables phase matching in dispersive media and paves the way for novel entanglement generation in silicon photonic devices.
