论文摘要
光学逻辑有可能用光电电路替换电子电路的应用，而光电到电动转换是不切实际的，并且用于整合的全光电电路。在耳语库模式谐振器中的非线性光学元件提供了低功率，可扩展的方法来实现光学逻辑。我们首次使用反传播光的全光通用逻辑门证明，所有信号都具有相同的操作光频率。这样的设备将使光信号的路由不需要转换为电子域，从而减小延迟。该设备的运行原理基于在耳语画廊模式谐振器中进行反向传播光束之间的KERR相互作用，该谐振器诱导了两个传播方向的共振频率之间的分裂。我们的门使用$ \ si {2e8} {} $的\ textit {q} {} $的融合二氧化硅微型谐振器。这种光学逻辑方法为光线布路由提供了实用的解决方案。
Optical logic has the potential to replace electronics with photonic circuits in applications for which optic-to-electronic conversion is impractical and for integrated all-optical circuits. Nonlinear optics in whispering gallery mode resonators provides low power, scalable methods to achieve optical logic. We demonstrate, for the first time, an all-optical, universal logic gate using counterpropagating light in which all signals have the same operating optical frequency. Such a device would make possible the routing of optical signals without the need for conversion into the electronic domain, thus reducing latency. The operating principle of the device is based on the Kerr interaction between counter-propagating beams in a whispering gallery mode resonator which induces a splitting between the resonance frequencies for the two propagating directions. Our gate uses a fused silica microrod resonator with a \textit{Q}-factor of $\SI{2e8}{}$. This method of optical logic gives a practical solution to the on-chip routing of light.
