Assignee: QUANZHOU SANAN SEMICONDUCTOR TECHNOLOGY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A light-emitting diode (LED), comprising:
a substrate which has an upper surface, a lower surface that is opposite to said upper surface, and a side surface connecting said upper surface and said lower surface;
a distributed Bragg reflector (DBR) structure which is disposed on said upper surface of said substrate; and
a semiconductor layered structure which is disposed on said DBR structure opposite to said substrate, and which is configured to emit a light having a first wavelength;
wherein said 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.
