我们报告了一个多峰分析的光子晶体L3腔研磨锂的独立膜。经典的L3腔的几何形状相比，包含第二晶格叠加在主要的L3腔。从垂直辐射和腔的每种模式的质量（Q）因子的角度研究了这两种不同的几何形状。取决于腔的几何形状，一些模式经历到小角度的垂直辐射的增强，而其他模式经历更高的Q因子。三维时域有限差分模拟证实了实验表征。(C)2013 AIP Publishing LLC.
We report on a multimodal analysis of photonic crystal L3 cavities milled in lithium niobate freestanding membranes. The classical L3 cavity geometry is compared to an L3 cavity containing a second lattice superimposed on the primary one. Those two different geometries are investigated in terms of vertical radiation and quality (Q) factor for each mode of the cavities. Depending on the cavity geometry, some modes undergo an enhancement of their vertical radiation into small angles while other modes experience a higher Q factor. Experimental characterizations are corroborated by three-dimensional finite difference time domain simulations. (C) 2013 AIP Publishing LLC.
