The present relates to a spatially modulated cladding mode stripper and to an optical fiber comprising a spatially modulated cladding mode stripper. The spatially modulated cladding mode stripper comprises a series of alternating high cladding light extracting regions and low cladding light extracting regions located along a portion of a cladding to modulate extracting of cladding light therefrom.

Spatially modulated cladding mode stripper and optical fiber therewith

A multi-wavelength laser source is provided including a pump laser unit, a gain section and an output. The pump laser unit generates an energy signal, which is applied to the gain section. The gain section includes a gain medium with having a superstructure grating forming a distributed Fabry-Perot-like structure. The superstructure grating causes a multi-wavelength laser signal to be generated when the energy signal is applied to the gain medium. The multi-wavelength laser signal is then released at the output.

A device for tailoring the chromatic dispersion of a multi-channel light signal is proposed. The device includes at least two waveguides coupled in a cascade, each provided with a spatially distributed optical filter. The group delay response of the filters is designed so that the group delay of each channel of the light signal can be tuned independently of the others, and an appropriate tuning mechanism is provided for this purpose. The device may advantageously be used as a flexible dispersion compensator.
