Dual-Wavelength Pumped Supercontinuum Generation in Tapered Photonic Crystal Fibers
By using 1064 nm pulsed laser the front section (77 cm) of photonic crystal fiber (PCF) is pumped and 747 nm signal light is got by four-wave mixing. The end part of the PCF is tapered and has two zero-dispersion wavelengths (ZDW). The 747 nm signal light and 1064 nm pulsed laser which locate in the anomalous dispersion regime between two zero-dispersion wavelengths are pumped into the tapered PCF. Supercontinuum with more than spectral width of 600~1700 nm (at 20 dB level) is generated in the tapered PCF which has 25 μm outer diameter and 27 cm length.
