SEMICONDUCTOR LASER MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor laser manufacturing method capable of improving yield.SOLUTION: A semiconductor laser manufacturing method is a method forming a resonator pattern including a first region having a diffraction grating pattern and a second region which is linked in a resonator length direction of the first region and has no diffraction grating pattern. The semiconductor laser manufacturing method comprises: a first process of providing a plurality of resonator patterns having lengths different from each other in the resonator length direction of the first region and arranged adjacent to each other in a direction crossing the resonator length direction; and a second process of leaving selected resonator patterns out of the plurality of resonator patterns and removing the other.SELECTED DRAWING: Figure 4
