Abstract

The Erbium doped fibre amplifier has effectively alleviated the problems of loss in the 1.5µm fibre telecommunications window, but its widespread adoption has meant using existing fibre links at wavelengths well away from their dispersion zero at 1.3µm. In order for error-free high data rate transmission over long distances of non-dispersion shifted fibre it is necessary to periodically undo the pulse-broadening effects of dispersion. An attractive technique for dispersion compensation is to use the dispersive properties of chirped fibre Bragg gratings to temporally re-focus the spectral components of short optical pulses. The high degree of control over fibre Bragg grating characteristics on a localised level permits the realisation of devices with unique dispersion profiles.
The use of linearly chirped fibre Bragg gratings for dispersion compensation in high speed non-soliton systems has recently been complemented by the first trials of fibre Bragg gratings for partial dispersion compensation in hybrid soliton/non-soliton transmission systems. The use of non-linearly chirped fibre Bragg gratings to provide 3rd order dispersion management in transmission systems low dispersion fibres is also envisaged to be of future importance in high speed WDM systems.
I will be discussing the design of fibre Bragg gratings for various dispersion compensation applications and shall present the results of a repeater-less transmission experiment over 1000km of non-dispersion shifted fibre using fibre Bragg gratings for partial dispersion compensation. I will go on to describe the effects of grating imperfections and time delay noise on the performance of transmission systems. A comparison of non-soliton systems with complete dispersion compensation and hybrid soliton/non-soliton systems with partial dispersion compensation will be made to address the levels of grating quality required for error-free operation
