Introduction: Tunable dispersion compensation is becoming inevitable for fibre-optic communication systems. Important applications include replacing conventional dispersion compensating fibres (DCFs) in long-haul transmissions, compensating residual dispersion after the DCF to meet the tight dispersion tolerances required in 40 Gbit=s and above based networks, and compensating thermallyinduced ...

We demonstrate two techniques to reduce the effects of fiber chromatic dispersion in fiber-wireless systems incorporating external modulators. We theoretically and experimentally show that the achievable link distance can be increased by varying the chirp parameter of the modulator to give large negative chirp using a dual-electrode Mach–Zehnder modulator (MZM) biased at quadrature. In addition...

We have proposed, fabricated and demonstrated experimentally a set of Coherent Direct Sequence-OCDMA en/decoders based on Super Structured Fiber Bragg Gratings (SSFBGs) which are able to compensate the fiber chromatic dispersion at the same time that they perform the en/decoding task. The proposed devices avoid the use of additional dispersion compensation stages reducing system complexity and ...

The apodization function plays an important role in the behavior of the mean dispersion, group delay and significant reduction of sidelobe level in reflection spectrum. On the other hand, the grating length represents as one of the critical parameters in contributing to a high performance fiber Bragg grating compensator. In this paper, we have investigated and compared the performances of vario...

We study the performance of a typical fiber-optic communication link operating at 10 Gbps, comprising of multiple spans of standard single mode fiber (SSMF), in-line amplifiers and dispersion compensating fibers (DCF). The effects of attenuation, chromatic dispersion, nonlinearity and polarization mode dispersion (PMD) are taken into account. By numerically solving the non-linear Schrodinger eq...

In this paper a microwave photonic filter using superstructured fiber Bragg grating and dispersive fiber is investigated. A theoretical model to describe the transfer function of the filter taking into consideration the spectral width of light source is established. Experiments are carried out to verify the theoretical analysis. Both theoretical and experimental results indicate that due to chr...

A general expression for the waveguide dispersion of a propagation mode is derived from wave equation. Furthermore, simple high-order modes as function field radius by substituting an approximated electrical distribution into expression. The chromatic dispersions LP01, LP11, LP02, and LP21 in four-mode fiber are estimated using proposed expression, their accuracies evaluated through simulations.

California Blvd., Pasadena, CA 91125, USA Abstract Diffraction gratings disperse light in a rainbow of colors with the opposite order than refractive prisms, a phenomenon known as negative dispersion [1, 2]. While refractiv...

This paper numerically investigated the evolution of the degree of polarization of individual channels and their Stokes parameters in a wavelength division multiplexed (WDM) system in which Kerr nonlinearity and chromatic dispersion are taken into account but in which polarization mode dispersion as well as polarization-dependent loss and gain are neglected. We compared the results to a mean fi...
