In this work, various dispersion compensation methods are designed and evaluated to search for a cost-effective technique with remarkable dispersion compensation and a good pulse shape. The techniques consist of different chirp functions applied to a tanh fiber Bragg grating (FBG), a dispersion compensation fiber (DCF), and a DCF merged with an optimized linearly chirped tanh FBG (joint techniq...

This paper presents a new circular photonic crystal fiber (C-PCF) for effective dispersion compensation covering E to L wavelength bands ranging from 1360-1625 nm. To investigate its guiding properties, finite element method (FEM) with a perfectly matched layer absorbing boundary condition is used. From our numerical simulation, it is found that the designed C-PCF simultaneously shows a large n...

We consider that Optical communication network offers very high potential bandwidth and flexibility In terms of high bit-rate transmission. However, their performance slows down due to some parameter like dispersion, attenuation, scattering and unsynchronized bit pattern. In long haul application, dispersion is the main parameter which needs to be compensated in order to provide high level of r...

We demonstrate a highly practical and robust soliton transmission system with partial dispersion compensation. Error free transmission was obtained for 10 Gb/s &ta over 1000 km of standard fibre with nominal dispersion of 17 ps/nrm km. Despite variations in the dispersion compensation ratio and the relatively high UV-induced birefiingence of the fibre gratings the system exhibits BERs below lo”...

Within the area of optical pulse propagation in long-haul transmission systems various designs for dispersion compensation are investigated. On the basis of variational procedures with collective coordinates, a very effective method is presented which allows to determine quite accurately the possible operation points. We have obtained an analytical formula for the Ž . soliton power enhancement....

A computationally efficient dispersion-folded (D-folded) digital backward propagation (DBP) method for nonlinearity compensation of dispersion-managed fiber links is proposed. At the optimum power level of long-haul fiber transmission, the optical waveform evolution along the fiber is dominated by the chromatic dispersion. The optical waveform and, consequently, the nonlinear behavior of the op...

Besides the phase and group velocities, the amplitude of guided wave mode is also frequency dependent. This amplitude dispersion also influences the performance of guided wave methods in nondestructive evaluation (NDE) and structural health monitoring (SHM). In this paper, the effects of amplitude dispersion to the spectrum and waveform of a propagating wave-packet are investigated. It is shown...

The effect of delay and reflectivity ripples of dispersion compensating fibre gratings on systems operated at 10 Gb/s over 100 km of standard single-mode fibre is investigated for partial or total dispersion compensation .

The effect of group-delay ripples in dispersion-managed soliton communication systems that use chirped fiber gratings for dispersion compensation is studied. Using both a reduced model and direct numerical simulation, we find that dispersion-managed solitons exist even in the presence of large dispersion variation caused by group-delay ripples. The dispersion-managed solitons suppress the growt...

The performance of DWDM 2x10.7Gbit/s-DQPSK is assessed comparing mid-link optical phase conjugation (OPC) and DCF for dispersion compensation. We report a 44%-increase in transmission distance resulting from nonlinear phase noise reduction by using mid-link OPC. Introduction Mid-link optical phase conjugation (OPC) is an attractive method for replacing chromatic dispersion compensating fiber (D...
