Abstract
A wide-band continuously tunable microwave photonic filter based on a novel multichannel chirped fiber Bragg grating is demonstrated. The four-tap filter demonstrates continuous tuning from 4.5 to 14 GHz through the use of uniquely incrementing dispersion profiles written within each channel of the grating. This allows for a simplified tuning method based on the collective wavelength tuning of a single multiwavelength optical source over a narrow wavelength range.
