Abstract
A method of fabricating a polymer optical circuit is provided. The method includes structuring a mold with a main mold and an auxiliary mold. The main mold has a first concavity corresponding to a first portion of the waveguide core, a second concavity corresponding to an end portion of the waveguide core with a specific shape, an injection hole for injecting a resin into the concavities, and a suction hole for suctioning-out the resin. The auxiliary mold has a shape corresponding to the specific shape of the end portion of the waveguide core. The method also includes firmly sticking a clad base film to a surface of the mold where the concavities are formed; filling the concavities with resin by injecting the resin via the injection hole and suctioning the resin via the suction hole; and forming the waveguide core by curing the resin.
