Abstract:
1. A method of manufacturing an optical module, the optical module including: a circuit board; an optical device mounted on the circuit board; and a resin member arranged on the circuit board and formed of a light-transmissive synthetic resin, wherein: the resin member includes: the optical device includes an optical device active layer adapted to emit or receive invisible light having a single wavelength of between 800 nm and 900 nm or 1260 nm and 1625 nm, and the lens is configured such that the invisible light transmitted through the lens forms an image of the optical device active layer at an optical fiber coupling plane, the optical fiber coupling plane being a plane at which an end surface of the optical fiber is located when the ferrule is attached to the sleeve, the method comprising the steps of: applying the invisible light onto the resin member and the optical device; observing a part of the resin member located at the optical fiber coupling plane and an image formed at the optical fiber coupling plane by the optical device active layer, with use of a camera, while applying the invisible light onto the resin member and the optical device; aligning positions of the resin member and the circuit board with respect to each other while observing the part of the resin member located at the optical fiber coupling plane and the image formed at the optical fiber coupling plane; and fixing the resin member to the circuit board while maintaining the aligned positions of the resin member and the circuit board.
