A waveguide type wavelength domain optical switch includes an input/output port including at least three waveguide spectrometers stacked in thickness direction, a first lens for collecting light outputted from an input port of the input/output port in one axis direction, a second lens for collecting light outputted from the first lens in a direction orthogonal to the collecting direction of the first lens, and an optical phase modulation cell for reflecting light outputted from the second lens through the second lens and the first lens to an output port of the input/output port. Alternatively, the input/output port may include at least two waveguide spectrometers and a waveguide optical coupler circuit stacked in thickness direction.
