Patent ID: 8675705

Claim:
A laser resonator for a laser diode, comprising: a gain section, a first planar Bragg reflector and a second planar Bragg reflector, wherein the gain section is arranged between the first planar Bragg reflector and the second planar Bragg reflector and wherein the width of a first portion of the gain section contacting the first planar Bragg reflector is larger than the width of a second portion of the gain section contacting the second planar Bragg reflector, wherein the entire gain section has a gain-guided design, and the width of the first planar Bragg reflector is smaller than the width of the first portion, wherein the width of the second portion is larger than the width of the first planar Bragg reflector and wherein the ratio of the width of the second planar Bragg reflector to the width of the first planar Bragg reflector is between 1.5 and 20.
