We survey the properties of photonic crystal fibers with elliptical air holes, examining mode shapes, birefringence, group velocity walkoff and dispersion, and cutoff conditions. We find new types of behavior for each quantity and demonstrate the possibility achieving large birefringence with zero walkoff in the single-mode regime. We show that the dispersive properties of the vector modes are closely tied to those of the so-called fundamental space filling modes, and that at long wavelengths, the fibers exhibit a single-polarization single-mode regime of propagation without the presence of material anisotropy.read more

Optical sensing with photonic crystal fibers
TL;DR: A review of optical fiber sensing demonstrations based on photonic crystal fibers is presented in this paper, which is orga- nized in five main sections: the first three deal with sensing approaches relying on fiber Bragg gratings, long-period gratings and interferometric structures; the fourth one reports applica- tions of these fibers for gas and liquid sensing; the last section focuses on the exploitation of nonlinear effects in pho- tonic crystal fibers for sensing.
