ABSTRACT:
Disclosed is a PCB in which a waveguide is embedded, and a method of producing the same. The PCB includes a substrate, and a lower clad layer formed on the substrate through a predetermined process to allow an optical signal irradiated thereto to be total-reflected thereby. A core layer is formed on the lower clad layer through a predetermined process and exposed using an exposing film on which a waveguide pattern is formed to form the waveguide with a predetermined shape therefrom. Furthermore, an upper clad layer is formed on the core layer through a predetermined process to allow the optical signal irradiated thereto to be total-reflected thereby.
