ABSTRACT:
A swept wavelength source for broad bandwidth Raman pump applications includes a source of ultrashort (e.g., picosecond) optical pulses. The pulse train output from the source is then applied as an input to a linear dispersive element (such as a section of negative dispersion-shifting fiber) which functions to “stretch” the ultrashort pulses, causing the pulses to become separated in time, with a continuous shift in the wavelength through the length of the pulse.
