摘要： PROBLEM TO BE SOLVED: To provide a method that facilitates manufacturing a vertically tapering core layer, wherein a film thickness is reduced as it is separated from a slab waveguide, with good reproducibility between array waveguides in the vicinity of the boundary of a channel waveguide array and the slab waveguide. SOLUTION: A core pattern, which is designed so that a space between the array waveguides is widened as it is separated from the slab waveguide, is formed by a photo-lithography technology and an etching technology. In this stage, formation of the vertical taper structure is not required, so that ordinary lithography technology and etching technology having good reproductivity can be used. Then, heat treatment at proper temperature is performed to deform cores, and a connection layer is formed between the cores. By designing the space between the array waveguides so that it is widened as it is separated from the slab waveguide, the thickness of a connection layer between the cores can be gradually reduced as it is separated from the slab waveguide only by applying heat treatment.
