Abstract
An optical interface module and a method for manufacturing an optical interface module. One method includes forming a lower clad layer on a first surface of a substrate, forming a core layer on the lower clad layer and forming two grooves in part of the core layer to form a first core part between the two grooves having one end and another end. Also included is forming an upper clad layer on the core layer and in the grooves, mounting a light-emitting element on the first surface and mounting a light-receiving element on the first surface of the substrate. A second core part is optically coupled to the light-emitting element and the first core part, and a third core part is optically coupled to the light-receiving element and the other end of the first core part.
