  • Patent number: 8103170
    Abstract: The present invention inputs a signal synthesized an optical pulse with a variable-wavelength laser beam different in wavelength from it to a delay unit (S1). The delay unit branches the signal to two optical signals, produces an optical path difference between them to afford a delay, synthesizes them again to generate a multiplexed optical signal, and minutely varies the optical path length of one of them (S2). The present invention measures output variance of the delay unit on a variable-wavelength laser beam resulting from the minute variance (S3), and controls the optical path difference so as to minimize output variance at a position where the output is a maximum or minimum, or is a specific value other than them (S4). This stabilizes a phase difference between adjacent pulses of the multiplexed optical signal outputted from the delay unit (5) with a simple construction in optical time division multiplexing technology.
