MULTIPLE WAVELENGTH SIGNAL LIGHT SOURCE, METHOD FOR GENERATING MULTIPLE WAVELENGTH SIGNAL LIGHT, OPTICAL WAVELENGTH CONVERSION DEVICE, AND METHOD FOR CONVERTING OPTICAL WAVELENGTH

摘要

PROBLEM TO BE SOLVED: To provide a multiple wavelength signal light source which generates multiple wavelength signal light by inputting an optical signal of an arbitrary modulation format and an arbitrary bit rate into an optical modulator driven by an electric signal applied from the outside and outputs wavelength conversion light, a method for generating the multiple wavelength signal light, an optical wavelength conversion device and a method for converting an optical wavelength.

SOLUTION: The multiple wavelength signal light source is provided with: the optical modulator to which the optical signal modulated with B [bit/s] transmission rate is inputted and which modulates the optical signal with the electric signal applied from the outside; and a repeating signal generator which generates an electric signal with a repeating frequency f [Hz] higher than the bandwidth of the optical signal and applies the resultant signal to the optical modulator. The multiple wavelength signal light with frequency interval f [Hz] is outputted from the optical modulator driven with f [Hz] modulation frequency by application of the electric signal.
