We report on the generation of an ultrabroad supercontinuum spanning from 400 nm to over 1750 nm in an extruded SF6 PCF with only 200 pJ pulses from an all-fiber Er laser-amplifier system.
We investigate a simple wavelength converter based on optical phase modulation. The scheme offers good efficiency, format- and bit-rate-independence and uses no local laser. Near penalty-free conversion, two-wavelength operation and a 100 nm operating range are confirmed.
Novel wavelength conversion technique by four-wave mixing inside a fiber Raman laser is proposed. By adopting highly-nonlinear dispersion shifted fibers, a high conversion efficiency and a wide conversion bandwidth are realized without an optical amplifier.
