Abstract
A method of manufacturing a two-dimensional (planar) optical waveguide comprises a first step of preparing a member having a thermoplastic structure (102) formed on a substrate (100), a second step of deforming the structure by heat treatment and a third step of forming an optical waveguide section (112) on the structure and the substrate.
