Problems solved by technology
[0007] However, in the design of the above-mentioned optical transmission coupling structure, the trench structure needs to be completed in its semiconductor substrate with a relatively complicated process; Assembling or implanting into the trench structure to export the optical signal out of the semiconductor substrate or the coupling device, or introducing it into the optical unit for transmission, is quite difficult and inconvenient, and even errors will occur, which in turn will make the optical signal The signal cannot be accurately reflected into the optical fiber or optical unit, so that the design of using light as the medium to transmit the signal will be affected

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 filmlayer 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 for receiving the optical signal reflected by the optical waveguide structure contained in an optical detection unit and converting the optical signal into the electric signal for transmission.
