提出了在半导体材料中制备棒连接金刚石（RCD）光子晶体结构。仅一个构建块的周期性移位可以产生复杂的三维网络，其中RCD结构表现出基于间隙/中间间隙（Δω/ωM）宽至0.20的全带隙。结构中的点缺陷腔由于其低对称性而在整个工作范围内维持单模谐振。对于11.5ax×4.25ay× 12 az的晶体，计算出谐振模的最高品质因子（Q因子）为1.5×104，ai（i=x，y，z）代表三个轴的周期长度。
Production of a rod-connected diamond (RCD) photonic crystal structure in a semiconductor material is proposed. Periodic shifting of only one building block can create a complicated three-dimensional network, with a RCD structure exhibiting a full bandgap as wide as 0.20 on a gap/midgap (Δω/ωM) basis. A point defect cavity in the structure sustains single-mode resonance throughout the operative range because of its low symmetry. The resonant mode’s highest quality factor (Q-factor) was calculated as 1.5×104 for a crystal of 11.5ax×4.25ay×12az for ai (i=x,y,z) representing three axes’ period lengths.
