Abstract:
1. A method for producing an oxide confined semiconductor laser, the method comprising the steps of: providing a laser chip layer including a substrate, a first distributed Bragg reflector formed on the substrate, an active layer formed on the first distributed Bragg reflector, and a second distributed Bragg reflector formed on the active layer; etching the second distributed Bragg reflector to form a semiconductor structure with a first and a second independent columnar platforms on the active layer; producing an oxide layer for the first and the second independent platforms; filling a dielectric layer between exteriors of the first and the second independent platforms to obtain a planarized surface; producing a protective layer disposed on the planarized surface of the dielectric layer and including a contact area hole corresponding to the first independent platform; producing a metal layer on the protective layer to form an area with a plated surface extended from the first independent platform to the second independent platform to serve as a pad for wire bonding the first independent platform; and producing a bottom electrode layer at bottom of the laser chip layer to form a cathode, so as to complete a production of an oxide confined dual platform vertical-cavity surface emitting laser (VCSEL).
