Abstract
An optical connector reduced in size and capable of reducing optical coupling losses when optical waveguides are connected to each other, and a method of manufacturing the same are provided. The optical connector comprises: an optical waveguide including cores for transmitting light, an under cladding layer provided under the cores, and an over cladding layer provided over the cores; and a ferrule section for optical connection provided in each end portion of the optical waveguide. Part of at least one of the over cladding layer and the under cladding layer lying in a location corresponding to each end portion of the optical waveguide is thick-walled to become the ferrule section for optical connection. A thin-walled part of the optical connector lying between the ferrule sections is an optical waveguide section. The optical connector requires no additional component as a ferrule, and is made small in size.
