PROBLEM TO BE SOLVED: To provide an optical signal reproducing device that can apply 3R reproduction to a signal. SOLUTION: The optical signal reproducing device is provided with an interferometer structure having two arms 11, 12. Each of the arms 11, 12 has a medium whose output optical power is changed, in response to an input optical power. The 1st arm 11 receives a continuous wave and a reproduced signal via an input coupling means 13. The 2nd arm receives continuous wave and a clock signal via the input coupling means 13. A filter 21, whose center frequency is matched with the conterminous wavelength receives an output signal from the interferometer structure 10 via a coupling means 14. The output signal of this filter configures a reproduced 3R signal. |
