چکیده:   (1577 مشاهده)
In this paper, we investigate for the first time the dispersion properties of photonic crystal fibers (PCFs) with a continuously-decreasing zero-dispersion wavelength (ZDW) along their length, via solving the eigen-value equation of the guided mode using the finite-difference frequency domain (FDFD) method. Since the structural parameters such as air-hole diameter d and the pitch Λ of the microstructured cladding change along the tapered PCFs, dispersion properties change with the fiber length as well. Therefore, it is important to know the exact behaviour of such characteristics along z which is necessary for nonlinear optics applications. We simulate the z-dependency of the ZDW along the tapered PCFs for various d and Λ and propose useful analytical relations for describing such characteristics. The results of this paper which are in a very good agreement with the available experimental ones, are important for simulating pulse propagation as well as investigating nonlinear effects such as supercontinuum generation and parametric amplification in tapered PCFs.
