Abstract
There is provided a resinous optical transmitting element in which a core, through which light is transmitted, is formed into a predetermined non-linear configuration, and a cladding lower in refractive index than the core is in close contact with the core. A method of manufacturing the optical transmitting element comprises the steps of polymerizing polymeric material forming the core, within a mold having a predetermined non-linear cavity, subsequently removing the mold, and forming the cladding about the core. The resinous optical transmitting element obtained by the method can be formed into a selected one of various configurations in compliance with the purpose. In addition, the resinous optical transmitting element is less in distortion, making it possible to reduce the transmission loss.
