PRODUCTION OF OPTICAL WAVEGUIDE ELEMENT

摘要

PURPOSE:To provide a production method of optical waveguide element which enables connection with an optical fiber without adjusting the axis of the core. CONSTITUTION:The waveguide element and optical fiber are fitted by using pins. The waveguide element is produced by such processes to form a waveguide comprising a clad layer 2 and a core layer on a substrate 1, to pattern the core layer to form a waveguide core 3 and a marker 4 at a specified distance from the waveguide core 3, and to form a groove for pin fitting on the substrate 1 by using the marker 4 as the reference.
