Classification: CPC H | IPC H

Claim 16:
17. A method of producing an LED, comprising the steps of:
(a) providing a substrate which has an upper surface, a lower surface that is opposite to the upper surface, and a side surface interconnecting the upper surface and the lower surface;
(b) forming a DBR structure on the upper surface of the substrate; and
(c) forming a semiconductor layered structure on the DBR structure opposite to the substrate, the semiconductor layered structure being configured to emit a light having a first wavelength;
wherein 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 which is different from the first wavelength.
