The features of lasing in three-dimensional photonic crystals like bulk opals and single-crystalline thin films based on silica nanospheres have been investigated. Random lasing in bulk opals with defect structure as feedback system has been showed. The realization of DFB-lasing in single-crystalline thin films with the periodic structure of photonic crystal as feedback system has been established. Radiation directivity has been narrower and lasing threshold has been almost three times less in the case of using single-crystalline thin films as compared to ones in the case of using bulk opals. Keywords:
3D photonic crystal, random lasing, distributed feedback.
