We present a novel single-polarization single-mode photonic crystal fiber (SPSM-PCF) design with four lines of small elliptical air-holes in order to obtain wider bandwidth for SPSM operation. The characteristics of the proposed SPSM-PCF are studied by using a full-vector finite element method (FEM) with perfect matched layer (PML) boundary conditions. At the wavelength of 1.55 µm, the confinement loss of the x-polarized mode is lower than 0.5 dB/km, whereas the loss of the y-polarized mode is larger than 50 dB/km. Compared with the case of x-polarized mode, the y-polarized mode can be suppressed in the PCF. Then, the SPSM operation is obtained. The proposed PCF can perform SPSM operation with broadband of 600 nm for considering the confinement loss ratio and the loss difference.

A novel high-birefringent photonic crystal fiber (PCF) was proposed and analyzed by full-vector finite element method (FEM). The modal field and birefringence properties were investigated. All of air holes in proposed PCF are round, and their diameters are the same. It is greatly reduce the difficulty of fabrication. According to the results of numerical analysis, it can be observed that the mode birefringence of this novel PCF can be easily achieve the order of 10-3at 1.55μm. This research provides effective theoretical method for the fabrication, development and construction of high-birefringence photonic crystal fiber.

Depending on the properties of photonic band gap materials, a novel photonic crystal fiber (PCF), formed by lithium niobate and liquid crystal, has been studied numerically. Dispersion relationships and transmission spectra of the PCF are calculated by methods of the full-vector modal and the finite difference time domain, respectively. The parameter-dependent dispersion and transmission of the PCF have been found. It is shown that the design of the novel photonic crystal fiber could be supported by the theoretical analysis in the paper.

Crossover And Mutation

A new method proposed in this paper to compute the fitness in Genetic Algorithms (GAs). In this new method the number of regions, which assigned for the population, divides the time. The fitness computation here differ from the previous methods, by compute it for each portion of the population as first pass, then the second pass begin to compute the fitness for population that lye in the portion which have bigger fitness value. The crossover and mutation and other GAs operator will do its work only for biggest fitness portion of the population. In this method, we can get a suitable and accurate group of proper solution for indexed profile of the photonic crystal fiber (PCF).
