Nondestructive distributed measurement of supercontinuum generation along highly nonlinear optical fibers. High quality of the depolarized supercontinuum laser output with a spectral bandwidth larger than 250 nm is readily achieved. Differently from previously demonstrated cw supercontinuum sources based on single propagation of a strong Raman pump laser beam through a highly nonlinear fiber, erbium gain inside the cavity generates a seed light oscillation, and the oscillated light subsequently evolves into a supercontinuum by nonlinear effects such as modulation instability and stimulated Raman scattering in the HNL-DSF.
The laser has a simple ring-cavity structure incorporating an erbium-doped fiber and a highly nonlinear dispersion-shifted fiber (HNL-DSF). We experimentally demonstrate a novel erbium-doped fiber based continuous-wave (cw) supercontinuum laser.
