FIELD: physics.
SUBSTANCE: light-emitting device includes the first and second cavity resonators. The first cavity resonator is provided with active layer wherein light generation is ensured through electric excitation. Light of related wavelength generated from the active layer is amplified by the second structure of distributed Bragg reflector and metal reflecting layer, so amplified light is transmitted to the second cavity resonator. The second cavity resonator is supplied with has wavelength conversion layer ensuring light conversion through optical pumping. Amplified light is converted by wavelength conversion layer into the light of the other wavelength, then amplified by the second structure of distributed Bragg reflector and the first structure of distributed Bragg reflector and brought out.
EFFECT: simplified generation of white light with higher quantum efficiency.
