Asymmetric forward and backward transmission through photonic structures can be achieved via optical nonlinearities, but existing systems have typically used slow thermo-optic effects. A new resonator design has now enabled low-loss, non-reciprocal pulse routing based on the Kerr nonlinearity in integrated silicon waveguides.

硅中的低损耗非线性光学隔离器

可以通过光学非线性来实现通过光子结构的不对称向前和向后传输，但是现有系统通常使用慢速热光效应。一种新的谐振器设计现已实现了基于集成硅波导中Kerr非线性的低损耗，不可逆脉冲路由。
