Patent number: 9929536Abstract: A vertical-cavity surface-emitting Laser (VCSEL) has a three-trench structure. By forming a first trench within a mesa around the periphery of an output window of the VCSEL, the overall capacitance is decreased and the time used in the oxidation process for an oxidation layer is shortened. By forming a second trench and a third trench on the periphery of the mesa in a step-like concave manner, the mesa becomes a step-like structure having double mesa-layers. Such that, a larger heat-radiating area can be obtained for decreasing thermal effects, while the metal-gap defects of the metal layer can also be avoided. The implant layer is formed around the periphery of the output window for controlling the optical mode and confining the current path. In addition, an output layer is formed on the output window for controlling the output light.Type: GrantFiled: June 15, 2017Date of Patent: March 27, 2018Assignee: TrueLight CorporationInventors: Bing-Cheng Lin, Chih Cheng Chen, Hung-Wei Tseng
