Chromatic dispersion compensation and Coherent Direct-Sequence OCDMA operation on a single super structured FBG.
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 ...
متن کاملDispersion Compensation using High-Positive Dispersive Optical Fibers
The common and traditional method for dispersion compensation in optical domain is concatenating the transmit optical fiber by a compensating optical fiber having high-negative dispersion coefficient. In this paper, we take an opposite direction and show how an optical fiber with high-positive dispersion coefficient can also be used for dispersion compensation. Our optical dispersion compensati...
متن کاملWideband Dispersion Compensation in Hexagonal Lattice Photonic Crystal Fiber
In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting elliptical holes in the first ring of the inner core clad of a dispersion compensating fiber of the hexagonal lattice, increases the wavelength ran...
متن کاملImplementation of CATV network using different Dispersion compensating Techniques
The main objective of the paper is to implementation of 16-QAM CATV (Community Antenna TV) system. To achieve this task, various dispersion compensation techniques that are more suitable for CATV system in the near future, are determine. It is necessary to use dispersion compensation devices .Dispersion compensation techniques have many advantages as a smooth dispersion profile (i.e. no dispers...
متن کاملWideband Dispersion Compensation in Square Lattice Photonic Crystal Fibe
In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting a combination of circular holes and a star structure in the inner core clad causes the dispersion coefficient profile to be broadened, and addition...
