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.

An extraction unit(130) receives the other one among the two optical carriers. The extraction unit extracts an optical carrier of a single polarization component. An optical coupler couples an optical carrier of a single polarization component with the DSB-SC signal.
