摘要
利用级联的线性电光效应对光进行控制是一种非常有效而且常用的控制光的手段。对于周期性畴反转铌酸锂(PPLN)一维光子晶体,在平行于光轴方向施加电场可周期性改变折射率大小,形成电光光子晶体结构;在垂直于光轴方向施加电场不仅可以改变折射率椭球大小,同时可以周期性改变折射率椭球主轴方向。综述了部分已报道的基于周期性的级联电光效应的应用,介绍了其在可调的手性器件、全光逻辑门、基于快慢光的时间隐身和非线性光学等方面的应用,展望了级联电光效应在未来集成光子芯片中的潜在应用。
Abstract
Controlling light based on cascading linear electro-optic effect is an effective and widely used method for light modulation. For an one-dimensional photonic crystal like periodically poled lithium niobate (PPLN), while electric field is applied parallel to the optical axis, the refractive index is periodically changed, and an electro-optic photonic crystal is formed. While electric field is applied vertically to the optical axis, not only the size of refractive index ellipsoid is periodically changed, but also the direction of spindle of refractive index ellipsoid is periodically changed. Some of the applications based on cascading electro-optic effect are reviewed, including tunable chirality devices, all optical logic gates, temporal cloak based on simultaneous fast and slow light, and nonlinear optics. The great potential applications of the cascading electro-optic effects in integrated photonic circuit are predicted.
