Terahertz waves have potential to enable larger capacity wireless transmission. One of the techniques to generate them is photomixing at a photodiode such as the uni-traveling diode (UTC-PD). To overcome the power saturation of the UTC-PD, we integrated two arrayed UTC-PDs to combine these powers. For practical use, the number of the UTC-PDs should be increased. And thus, the integration technology of the input optical waveguides and the UTC-PDs has to be developed. We propose the photonics integration device consisting of the input optical waveguide and the evanescently coupled UTC-PD.
