Abstract:
1. A method of manufacturing an optical element comprising the steps of: forming a layer of a template-forming resin material to an original substrate in which convexes for optical waveguide channel are formed, then peeling the same to form a mold, and then cutting both ends of the mold to expose concaves corresponding to the convexes for optical waveguide channel formed to the mold, thereby preparing a template; closely adhering a flexible film substrate for clad having good adhesion with the template to the template; bringing one end of the template which is adhered with the flexible film substrate for clad into intimate contact with a UV-ray curable resin or a thermosetting resin to form a core and making the UV-ray curable resin or the thermosetting resin intrude by a capillary phenomenon into the concaves of the template; curing the intruded UV-ray curable resin or the intruded thermosetting resin and peeling the template from the flexible film substrate for clad; and forming a clad layer on the flexible film substrate for clad formed with the core, thereby preparing a flexible polymeric optical waveguide channel sheet and then attaching a light receiving portion to the end face of the sheet.
