Abstract: An apparatus and method for performing optical alignment between optical waveguide elements in manufacturing a surface mountable optical module, in which a plurality of optical waveguide elements are mounted on a surface of a mounting substrate, is disclosed. A controller performs recognition of the interference pattern included in the image information received from the camera, observes parallelism between the substrate support and the mounting substrate and between the mounting substrate and the optical waveguide element using the recognized pattern, generates a control signal to control the transport device according to the observed parallelism, and transmits the control signal to the transport device to perform control of the optical waveguide element.
