摘要： 我们设计并演示了一种紧凑且低功耗的带工程化电光（EO）聚合物填充的硅槽光子晶体波导（PCW）调制器。 EO聚合物经过工程化设计，具有大的EO活性和近红外透明性。 使用PCW阶跃耦合器以实现与带工程化PCW慢光模式的最佳耦合。 在8nm的光谱范围内测得半波切换电压为V{\pi }=0.97+-0.02V，对应于器件内有效的r33为1190pm/V和推挽配置下的V{\pi } L为0.291+-0.006V mm。 不考虑慢光效应，我们估计在槽中EO聚合物的极化效率为89pm/V。 显示英文摘要

摘要： We design and demonstrate a compact and low-power band-engineered electro-optic (EO) polymer refilled silicon slot photonic crystal waveguide (PCW) modulator. The EO polymer is engineered for large EO activity and near-infrared transparency. A PCW step coupler is used for optimum coupling to the slow-light mode of the band-engineered PCW. The half-wave switching-voltage is measured to be V{\pi}=0.97+-0.02V over optical spectrum range of 8nm, corresponding to the effective in-device r33 of 1190pm/V and V{\pi} L of 0.291+-0.006V mm in a push-pull configuration. Excluding the slow-light effect, we estimate the EO polymer is poled with an efficiency of 89pm/V in the slot.
