In contrast with conventional optical fibers, photonic crystal fibers (PCF) present a diversity of new
and improved features, which provide several new applications such as nonlinear fiber optics, fiber
lasers, supercontinuum generation, and fiber sensors. In many applications of all-optical signal
processing, optical fibers with both high birefringence and high nonlinearity are desired, because
many nonlinear effects in optical fiber are polarization-sensitive, and maintaining the state of
polarization (SOP) is essential for good performance. In particular, with enhanced nonlinearity, both
the footprint and power-consumption of optical device can be reduced. By carefully arranging the air
holes of PCF, high birefringence in excess of 103 can be readily achieved
