PROBLEM TO BE SOLVED: To provide an optical continuum source including light generation beyond wavelength edges of continuum.;SOLUTION: An optical continuum source is formed that is used to generate both a continuum and one or more light peaks outside the bandwidth of the continuum. In particular, one or more fiber Bragg gratings 18 exhibiting a resonant wavelength less than the short wavelength edge (or greater than the long wavelength edge) of a prescribed continuum are inscribed into a section of highly nonlinear fiber (HNLF) and used to generate the additional light peaks. Gratings may also be formed for areas along the fiber where the continuum power density is essentially "zero". The use of a Bragg grating generates phase matching with the propagating optical signal, thus resulting in the creation of the additional peaks.;COPYRIGHT: (C)2009,JPO&INPIT
