1. An optical device comprising:
a laser light source; a first optical waveguide propagating light, the light being output from the laser light source; a first distribution device distributing the light into n lights (n is an integer equal to or more than two), the light being input from the first optical waveguide; n second optical waveguides propagating the n lights, the n lights being output from the first distribution device; n second distribution devices distributing the n lights being propagated through the n second optical waveguides, each of the n second distribution devices distributing light propagated through each of the n second optical waveguides into m lights (m is an integer equal to or more than two); n×m third optical waveguides propagating n×m lights, the n×m lights being output from the n second distribution devices; a plurality of control electrodes applying voltage or current to each of the n×m third optical waveguides individually, and control phase of each of light propagating through the n×m third optical waveguides individually; and an output end surface outputting n×m lights, the n×m lights being propagated through the n×m third optical waveguides.
