Experimental reduction of chromatic dispersion effects in lightwave microwave/millimetre-wave transmissions using tapered linearly chirped fibre gratings

It is demonstrated experimentally that the dramatic microwave-power degradation that appears in conventional 1550 nm lightwave amplitude modulated systems, due to chromatic dispersion, may be overcome by using tapered linearly chirped fibre gratings. An extension of the frequency-length product of fibre links in optical microwave/millimetre-wave systems can be achieved using chirped fibre gratings.
