Transmitting terminal module and receiving terminal module with optical waveguide structures

The invention relates to a transmitting terminal module and a receiving terminal module with optical waveguide structures, applied to the conversion and the transmission of an electric signal or an optical signal. The transmitting terminal module comprises a semiconductor substrate, a first film layer, an electric signal transmission unit, a light source unit, a second film layer and an optical waveguide structure, wherein the light source unit is used for receiving an electric signal, converting the electric signal into an optical signal and transmitting the optical signal, and one reflecting surface of the optical waveguide structure corresponds to the light source unit so that the optical signal can penetrate through the first film layer, the semiconductor substrate and the second film layer to enter the optical waveguide structure, and be reflected by the reflecting surface to enter an optical waveguide structure main body for transmission. The receiving terminal module has a similar structure and is used
