Abstract The present invention relates to microwave and laser device, and especially micro cavity laser. The present invention constitutes photon crystal micro cavity by utilizing point faults and linear faults and the point faults and the stimulating medium inside the faults constitute active resonant cavity. By regulating the distance between the point fault and the linear fault second the number of the "atoms" in between, the radiation energy inside the resonant avity may be coupled to waveguide in almost 100 %. The present invention makes it possible to concentrate the radiation energy to any position inside the waveguide and may be applied in the design of cavity for semiconductor laser and the light source and waveguide for integrated light path.
