Integrated optical waveguide and method for manufacturing same

摘要

An integrated optical waveguide is obtained by forming a plurality of independent optical waveguides within a single optically-transparent flat plate, markedly reducing crosstalk. In the integrated optical waveguide obtained by forming a plurality of independent optical waveguides within a single optically-transparent flat plate, dummy optical waveguides are provided between individual adjacent optical waveguides. An integrated optical waveguide having an isolation of 30 dB or higher is obtained. <IMAGE> <IMAGE> <IMAGE> <IMAGE>
