METHOD FOR GENERATING A PHASE-ACCORDING SPECTRUM-SPECTRUM LARGE SOURCE INCLUDING LEAK MODES

摘要

The invention relates to an optical waveguide (10) for propagating an original light signal, comprising a first nonlinear waveguide core (12), characterized in that said first core is capable of generating leakage modes from said original light signal.Through the waveguide as described above, in particular due to the nonlinearities of the first guide core, a continuum of light can be generated within the fiber according to the invention by colinear phase tuning. Moreover, by Cerenkov effect, other wavelengths are generated by the wavelengths of the continuum by non-collinear phase agreement.
