  • Light emitting device
    Patent number: 10930815
    Abstract: A light emitting device includes a light emitting structure and a distributed Bragg reflector (DBR) structure disposed thereon. The light emitting structure includes an n-type confinement layer, an active layer disposed on the n-type confinement layer, and a p-type confinement layer disposed on the active layer opposite to the n-type confinement layer. The n-type and p-type confinement layers are disposed proximal and distal to the DBR structure, respectively. The DBR structure includes first to Nth DBR units. The first and Nth DBR units are disposed proximal and distal to the light emitting structure, respectively. Each of the first to Nth DBR units has a center reflection wavelength defined by ?+(z?1)?0.
