We design an intersection for crossing waveguides in triangular lattice photonic crystals with cross-talk smaller than 10(-5). The cross-talk to the transverse waveguides is suppressed by symmetry mismatch between the cavity mode and the waveguide mode or by the mode-gap effect induced by air hole radius modulation of the waveguides. The transmission behavior of the crossing waveguides are illustrated by numerical simulations through finite difference time domain method.
我们设计了一种用于三角形晶格光子晶体中交叉波导的交叉点,其串扰小于10^(-5)。通过腔模与波导模之间的对称性失配或通过波导气孔半径调制引起的模隙效应,抑制了对横向波导的串扰。通过有限差分时域方法的数值模拟,说明了交叉波导的传输行为。
