从氧化锆反蛋白石光子晶体结构的激光渗透的罗丹明染料的解决方案被发现表现出单模激光峰的光谱宽度小于1 nm和品质因数超过4000。该激射发生在与光子阻带相关的高反射率光谱区的近似范围内，沿沿着[111]晶向，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。这种激光机制可用于实现可调谐单模光子晶体激光器。
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.
