Abstract: PURPOSE: A waveguide type photomixer is provided to reduce a moving distance of an electron-hole pair and a RC time constant. CONSTITUTION: A waveguide type photomixer(100) includes a substrate(101), a buffer layer(102), a first cladding layer(107), an absorber(110), a second clad layer(108), a contact layer(109), a first electrode unit(103), and a second electrode unit(104). The absorber is formed between the first clad layer and the second clad layer. If the absorber forms a junction area smaller than the first clad layer and the second clad layer, a RC time constant, which determines an operation speed of the photo mixer, becomes smaller and the operation speed of the photo mixer increases.
