ABSTRACT:
An optical waveguide manufacturing method which obviates a developing step and stably provides greater differences in refractive index between a core and cladding layers. A core formation photosensitive resin layer is formed on a surface of an under-cladding layer, and then exposed in a predetermined pattern. A core is formed which is defined by an exposed portion of the core formation photosensitive resin layer. Surfaces of the exposed portion and an unexposed portion of the core formation photosensitive resin layer are covered with an over-cladding layer formation photosensitive resin layer. The two photosensitive resin layers are heated, whereby a resin of the unexposed portion of the core formation photosensitive resin layer and a resin of the over-cladding layer formation photosensitive resin layer are melt-mixed together to form a mixture layer. Then, the mixture layer is exposed, whereby a third cladding layer is formed defined by the exposed mixture layer.
