ABSTRACT
The generation of wavelengths above 3 µm by nonlinear processes in short silica photonic crystal fibers is investigated numerically. It was found that wavelengths in the 3-3.5 µm range may be generated quite efficiently in centimeter-long fiber pieces when pumping with femtosecond pulses in the 1.55-2 µm range. Wavelengths in the range of 3.5-4 µm can in principle be generated, but these require shorter fiber lengths for efficient extraction. The results indicate that useful 3 µm sources may be fabricated with existing silica-based fiber technology.
