METHOD FOR MANUFACTURING OPTICAL WAVEGUIDE CHIP

摘要

A method for manufacturing an optical waveguide chip is provided. The optical waveguide chip is provided with an optical waveguide which does not generate peeling, cracks, etc. under severe use conditions and stably maintains excellent transmission characteristics for a long period of time, and a robust optical fiber guide part which matches with a shape and sizes of an optical fiber and does not generate cracks. The optical waveguide chip (1) includes a substrate (5), the optical waveguide (3) composed of a core part (7) and clad layers (6, 8), the optical fiber guide part (4) for positioning the optical fiber connected with the optical waveguide (3), and a cover member (glass board) (5). The optical waveguide (3) is made of a photosensitive polysiloxane composition. The optical fiber guide part (4) is made of the same photosensitive composition as that of the optical waveguide (3) or a photosensitive composition different from that of the optical waveguide (3). The optical waveguide (3) and the optical fiber guide part (4) are formed in different processes.
