摘要： A wavelength division multiplex type mode-lock laser device which simultaneously generates high-speed optical pulse trains for more than one wavelength. This device simultaneously generates high-speed optical pulse trains at two or more wavelengths. A ring resonator type mode-lock laser device or a Fabry-Perot type mode-lock laser device is modified so that it has an optical path difference providing structure which provides different refractive indices for the polarization directions which are at right angles at one another. This enables configuring a resonator corresponding to the optical path lengths formed according to the refractive indices and hetero-wave length optical path equalizing means to provide different refractive indices for different wavelengths.

摘要： A multiple-channel all-optical TDM-WDM converter and multiple-channel all-optical TDM demultiplexer which is able to simultaneously and spatially separate optical signal pulse trains of each channel from a TDM optical signal pulse train is structured without using a multistage-structure constitution. A control optical source 10 generates a control optical pulse train containing N optical frequencies, which is synchronous with optical signal pulse trains of N channels which are to be divided from a TDM optical signal pulse train wherein optical signal pulse trains of N channels have been multiplexed in time series. An optical wavelength multiplexer 11 combines the time-division-multiplexed optical signal pulse train and the control optical pulse train. The light output from an optical wavelength multiplexer 11 is input to a nonlinear material 12, which induces a four-wave mixing effect between the control optical pulse stream having the N optical frequencies and optical signal pulse trains of N channels, and outputs a frequency-converted optical pulse train which is the combination of N optical pulse trains having different optical frequencies. An optical wavelength demultiplexer 13 spatially divides the N types of optical pulse trains according to each optical frequency from the frequency-converted optical pulse train.

摘要： High peak pulse light is incident on an optical fiber having a dispersion decreasing region which serves as a main region for generating supercontinuum or idler light and in which the chromatic dispersion does not increase but at least partially decreases in the direction in which light travels. The fiber can be applied to broad band width idler light generation with both light transmission directions. Four wave mixing upon incidence of the light on the dispersion decreasing region of the optical fiber are efficiently obtained.
