a substrate, a planar optical waveguide provided on the substrate, a light source that emits light to the planar optical waveguide, a first planar lens that converts the light propagating within the planar optical waveguide into parallel light; a light deflecting means arranged outside the light and deflecting the parallel light in accordance with the frequency of the input electrical signal; a second plane lens condensing the polarized light from the light deflecting means; and the second plane. a photodetector that detects the light focused by the lens; and a second plane lens that is provided at a certain angle to the surface of the substrate in contact with the photodetector and that is not deflected by the light deflecting means. A waveguide type optical/acoustic spectrum analyzer characterized by having an inclined end face that removes focused unpolarized light.
