Influence of temperature on dispersion properties of photonic crystal fibers infiltrated with water

Abstract

Temperature change of the water infiltrated PCF is an interesting and practical method for a dynamical fine tuning of dispersion in active dispersion shift compensating systems. In this paper we present a numerical study on the influence of the temperature of infiltrated water on the dispersion and modal characteristics of photonic crystal fiber. We study regular hexagonal lattice photonic crystal fibers with various geometrical parameters using finite element method.

Dispersion and nonlinearity properties of small solid-core photonic fibers with As2Se3 substrate

“…Although silica PCFs have extensively been studied with numerous advantages, silica has a weak nonlinear index. More importantly, any optical applications of silica PCFs should not exceed the limit of 2 µm of wavelength because of their intrinsic losses [17][18][19][20][21]. Therefore, non-silica glass PCFs must be expected to enhance the application of microstructured optical fibers.…”

Supercontinuum generation in helically twisted photonic crystal fibers with a solid core

“…Meanwhile, the low dispersion can be easily controlled by tailoring its structure, namely the lattice constant and air hole diameter [14]. Several aspects of the exclusive dispersion behavior in PCFs have already been identified, including the ultra-flattened dispersion characteristic [22], ZDW shift [23], and chromatic dispersion optimization [19]. For example, by increasing the diameter of the air holes when the lattice pitch is constant, the ZDW shifts to shorter wavelengths and the region of anomalous dispersion increases [24], which also leads to an increase in the difference between the maximum and minimum dispersion values in the area of its non-monotonic region [14].…”
