In this Letter we demonstrate broadband electro-optic modulation with frequencies of up to 40 GHz in slotted photonic crystal waveguides based on silicon-on-insulator substrates covered and infiltrated with a nonlinear optical polymer. Two-dimensional photonic crystal waveguides in silicon enable integrated optical devices with an extremely small geometric footprint on the scale of micrometers. The slotted waveguide design optimizes the overlap of the optical and electric fields in the second-order nonlinear optical medium and, hence, the interaction of the optical and electric waves.
在这封信件中,我们展示了基于覆盖和渗透有非线性光学聚合物的绝缘体上硅衬底的开槽光子晶体波导中的高达 40GHz 的宽带电光调制。硅基二维光子晶体波导可实现极小的几何尺寸(在微米量级)的集成光学器件。开槽波导设计优化了二阶非线性光学介质中光场和电场的交叠,从而优化了光波和电波的相互作用。
