PROBLEM TO BE SOLVED: To provide a wavelength switching semiconductor light source that performs high-speed wavelength switching operation without being limited to a carrier life time. SOLUTION: The wavelength switching semiconductor light source that switches the wavelength of light to be output includes a first phase control optical waveguide 100 equipped with a first phase control optical waveguide electrode 102, a second phase control optical waveguide 101 equipped with a second phase control optical waveguide electrode 103, and a semiconductor Mach-Zehnder type optical switch 120 having a first optical multiplexer/demultiplexer 104A coupled to one end side of the first phase control optical waveguide 100 and one end side of the second phase control optical waveguide 101 and a second optical multiplexer/demultiplexer 104B coupled to the other end side of the first phase control optical waveguide 100 and the other end side of the second phase control optical waveguide 101, wherein the semiconductor Mach-Zehnder type optical switch 120 switches the wavelength of the light to be output.
