Abstract:
A vertical resonator laser diode, comprising:a main surface; two Bragg reflector sequences including a first Bragg reflector layer sequence having a plurality of mirror pairs and a second Bragg reflector layer sequence having a plurality of mirror pairs and defining part of said main surface, said two Bragg reflector layer sequences forming a laser resonator; an active layer sequence having a pn junction and serving for generating laser radiation, said active layer sequence disposed between said first Bragg reflector layer sequence and said second Bragg reflector layer sequence; a contact-making zone having a relatively high electrical conductivity and a surface defining part of said main surface, said contact-making zone extending from said main surface at least as far as said pn junction for making a conductive connection with said first Bragg reflector layer sequence; two mutually insulated, electrical connection contacts applied to said main surface, said two Bragg reflector layer sequences and said active layer sequence disposed in a current path between said two mutually insulated, electrical connecting contacts, said two mutually insulated, electrical connection contacts include a first electrical connecting contact connected to said second Bragg reflector layer sequence, and a second electrical connecting contact disposed on said contact-making zone and coupled to said first Bragg reflector layer sequence though said contact-making zone; and an insulation layer electrically insulating said contact-making zone from said second Bragg reflector layer sequence and from said active layer sequence.
