摘要

本文通过改变单晶的本构材料，设计了一种基于光子晶体的带通滤波器，以满足ITU-T推荐的CWDM系统G.694.2。结果表明，Si1-xGex合金与氮化硅(Si3N4)的共融可以代替Si/SiO2对形成单晶胞的原始层。最后给出了CST - MW模拟结果，以比较为目的，证明了Si1-xGex/Si3N4对作为光子晶体的基础比Si/SiO2对更优越。

Photonic crystal based flat-top filter for CWDM channel compatible with ITU-T recommendation G.694.2

In this paper a photonic crystal based band pass filter has been designed to meet ITU-T recommendation G.694.2 for CWDM system, by varying the constitutive materials of the unit cell. The amalgamation of Si_1-xGe_x alloy, with Silicon Nitride (Si₃N₄) has been effectively found compatible as primitive layers of unit cells instead of Si/SiO₂ pair. Finally CST MW simulated results have been presented, for comparative purpose, to demonstrate the amenities of Si_1-xGe_x/Si₃N₄ pair, over Si/SiO₂ pair, as basis of the photonic crystal.
