Abstract
A light-emitting diode includes a substrate, a distributed Bragg reflector (DBR) structure and a semiconductor layered structure. The DBR structure is disposed on the substrate. The semiconductor layered structure is disposed on the DBR structure opposite to the substrate, and is configured to emit a light having a first wavelength. The DBR structure has a reflectance of not greater than 30% for the light having the first wavelength, and a reflectance of not smaller than 50% for a laser beam having a second wavelength that is different from the first wavelength.
