Abstract:
1. A vertical cavity surface emitting laser device comprising: a bottom distributed Bragg reflector; a top distributed Bragg reflector; an active layer formed between the bottom distributed Bragg reflector and the top distributed Bragg reflector, arranged for generating laser light with a predetermined emission wavelength; at least one oxide section formed between top distributed Bragg reflector and active layer; a top electrode layer with a first window exposed formed above the top distributed Bragg reflector; a first heat dissipation layer sandwiched between the top distributed Bragg reflector and the top electrode layer; and a contact layer formed between the top electrode layer and the first heat dissipation layer, and a graded index layer formed between the top distributed Bragg reflector and the first heat dissipation layer.
