a March-Zenhder interferometer unit(61) for delaying the light, which is moving to one of its arm, for a half period than the light, which is moving to another arm; an optical divider unit(63) for dividing the interferometer output into two; and a control unit(64) for outputting a control signal to the interferometer using the output of the divider to do a phase modulation so as to achieve a high speed optical communication. |
