We present the design and analysis of a novel reconfigurable photonic-crystal waveguide (PCW). The predefined waveguide is the result of the refractive-index variation of three rows of holes that can be obtained by the infiltration of liquids within what are otherwise air holes in a two-dimensional triangular-lattice photonic crystal. We compute the power transmission through the reconfigurable PCWs as well as through arbitrary waveguide bends. The advantages of writing reconfigurable PCW of a multimode nature are highlighted. We demonstrate the necessity to infiltrate high-refractive-index substances to obtain efficient power transfer via reconfigurable manner.
我们展示了一种新型可重构光子晶体波导（PCW）的设计与分析。预定义的波导是三排孔折射率变化的结果，这可以通过在二维三角晶格光子晶体中原本为气孔的孔内注入液体来实现。我们计算了通过可重构PCW以及任意波导弯曲处的功率传输。突出了写入多模性质的可重构PCW的优点。我们证明了注入高折射率物质以通过可重构方式获得高效功率传输的必要性。
