Dual-Wavelength-Pumped Supercontinuum Generation in an All-Fiber Device

We experimentally demonstrate supercontinuum generation with a novel dual-wavelength pumping scheme. The dual-wavelength pump source and supercontinuum generation were realized one after another in a fusion spliced all-fiber device. The spectrum, extending from as short as 360 nm to beyond 1750 nm, is very flat. The all-fiber configuration makes the source very compact.
