Abstract

Compared with the edge emission laser, the vertical-cavity surface-emitting laser (VCSEL) with better beam quality can be performed more efficiently coupling with optical fiber. The 650nm~670nm wavelength VCSEL can be widely used in plastic optical fiber (POF) network source. This paper introduces a new kind VCSEL with new structure, of which the thermal characteristic is better than tradition device. In the special structure of the laser, the thickness of the substrate under the active region is lower, the heat generated by the laser can be faster transferred to the heat sink and the cooling effect is enhanced. In addition, the series resistance of the device is smaller and the heat produced by the device is further reduced. Through comparative test with the traditional VCSEL, the light output power of the device with new structure is increased by more than 20%.
