Supercontinuum generation in a water-core photonic crystal fiber.
June 27th, 2008 | by admin |Supercontinuum generation in a water-core photonic crystal fiber.
Supercontinuum generation is demonstrated in a 5-cm-long water-core photonic crystal fiber pumped near water\’s zero-dispersion wavelength. Up to 500-nm spectral width (evaluated at -20 dB from the peak) is achieved, while spectral widths were over 4 times narrower with a bulk setup at the same wavelength and peak power, and over 3 times narrower if the PCF was pumped away from the zero-dispersion wavelength. The supercontinuum generation mechanisms for bulk and waveguide setups are compared and tuning of the zero-dispersion wavelength via waveguide dispersion is theoretically investigated.
