Method for manufacturing semiconductor optical device, method for manufacturing can-type optical module, and semiconductor optical device

Abstract

A method for manufacturing a semiconductor optical device includes: forming two semiconductor optical devices, each of which includes a waveguide including an oblique waveguide portion extending obliquely with respect to a front-end surface, in a semiconductor substrate so that the front-end surfaces of the two semiconductor optical devices face each other; forming a light emitting point recognition pattern, which extends from one of the two semiconductor optical devices to the other through a border region of the two semiconductor optical devices, on a surface of the semiconductor substrate; and cleaving the semiconductor substrate within the border region to separate the two semiconductor optical devices.
