Lasing from zirconia inverse opal photonic crystal structures infiltrated by solutions of rhodamine dyes was found to exhibit single-mode lasing peaks with spectral width less than 1 nm and quality factor in excess of 4000. The lasing occurs within the approximate range of high-reflectance spectral region associated with photonic stop band along [111] crystallographic direction, but its wavelength is not fixed to the corresponding Bragg wavelength of the periodic structure, and depends on the spectral position of the gain band. This lasing regime can be useful for realizing tunable single-mode photonic crystal lasers.
研究发现，用罗丹明染料溶液渗透的氧化锆反蛋白石光子晶体结构产生的激光，其单模激光峰的光谱宽度小于1nm，品质因数超过4000。激光出现在沿[111]晶向与光子禁带相关的高反射光谱区域的近似范围内，但其波长并不固定于周期结构的相应布拉格波长，而是取决于增益带的光谱位置。这种激光模式对于实现可调谐单模光子晶体激光器可能是有用的。
