Abstract
To provide a light-emitting device having a resonator capable of stably and efficiently taking out light. The device includes an active medium, a resonator for confining the light having a first wavelength emitted from the active medium within a three-dimensional space and a wavelength conversion medium for converting the wavelength of the light having the first wavelength into a second wavelength.

8. A light-emitting device comprising:
-
a resonator comprising a three-dimensional photonic crystal, a wavelength conversion medium, a first active medium generating a light of a first wavelength, and a second active medium generating a light of a second wavelength different from the first wavelength, wherein the light of the first wavelength and the light of the second wavelength are converted into a light of a third single wavelength by the wavelength conversion medium and then emitted to the outside of the resonator.
