Silicon photonic package and method of fabricating the same

Abstract

A silicon photonic package and a method of fabricating the package are disclosed. The silicon photonic package includes an optical waveguide structure, a heat dissipation structure, a plastic encapsulation layer, first and second structures. The optical waveguide structure is a right trapezoidal structure, and a surface where a non-right angle leg thereof is a totally reflecting surface capable of totally reflecting an optical signal that enters the optical waveguide structure from a surface where a right angle leg is disposed in a direction parallel to bases to a plane where a front face of the plastic encapsulation layer is disposed. The heat dissipation structure and the optical waveguide structure are spaced apart from each other and both embedded in the plastic encapsulation layer. The optical waveguide structure of the present invention allows a great reduction in loss of an optical signal incurred by its propagation in the optical waveguide structure.
