[email protected] Abstract: Presented is an analysis of general scaling perturbations in a transmitting fiber. For elliptical perturbations, under some conditions an intermode dispersion parameter characterizing modal PMD is shown to be directly proportional to the mode dispersion. c © 2008 Optical Society of America OCIS codes: (060.24000) Fiber properties ; 060.2280 Fiber design and fabrication

Analysis of general geometric scaling perturbations in a transmitting waveguide: fundamental connection between polarization-mode dispersion and group-velocity dispersion
We develop a novel perturbation theory formulation to evaluate polarization-mode dispersion (PMD) for a general class of scaling perturbations of a waveguide profile based on generalized Hermitian Hamiltonian formulation of Maxwell’s equations. Such perturbations include elipticity and uniform scaling of a fiber cross section, as well as changes in the horizontal or vertical sizes of a planar w...

A complete diallel cross of nine cotton genotypes (Gossypium hirsutum L. & Gossypium barbadense L.) viz Delinter, Sindose-80, Omoumi, Bulgare-539, Termez-14, Red leaf (Native species), B-557, Brown fiber and Siokra-324 having diverse genetic origins was conducted over two years to determine the potential for the improvement of yield, its components, oil and fiber qual...
متن کاملCorrelation theory of polarization mode dispersion in optical fibers
A general theory is used to describe the correlation properties of polarization mode dispersion (PMD) in a birefringent, linear, dispersive medium such as optical fibers. The theory includes the effects of frequency dependence of birefringence on all orders, and it is capable of providing statistical information about secondand higher-order correlations among the polarization and PMD vectors. W...
متن کاملPolarization Changes in Optical Fibers induced by Self-Phase Modulation and Cross-Phase Modulation in Conjunction with Birefrigence
Polarization dependence of various fiber effects affecting signal quality in wavelength division multiplexing (WDM) systems has become a major field of research activities. Polarization– mode dispersion (PMD) and polarization–dependent loss (PDL) are quite well understood today, but there are still major open questions with respect to the interaction with nonlinear fiber effects, although the p...
متن کاملEvaluation of Hybrid Fiber Reinforced Concrete Exposed to Severe Environmental Conditions
Hybrid fiber reinforced concrete (HFRC) consisting of two or more different types of fibers has been widely investigated because of its superior mechanical properties. In the present study, the effect of the addition of steel (0.25%, 0.5%, 0.75%, and 1% of concrete volume) and Polypropylene (0.2%, 0.4%, and 0.6% of concrete volume) fibers on the surface scaling resistance of concrete, depth of ...
