SELF-ALIGNED INDEX GUIDE TYPE BURIED HETEROSTRUCTURE NITRIDE LASER STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a laser diode having a stronger mode stability and a low threshold current operation.

SOLUTION: The index guide type heterostructure nitride laser structure 100 has a first waveguide layer, a second waveguide layer, a multiple quantum well structure 145 interposed between the first and second waveguide layers, a ridge structure 111 having first, second and third faces, and a buried layer 155 existing on the first, second and third faces of the ridge structure 111.
