Abstract : We have demonstrated a tapped delay line microwave filter based on the use of high dispersion fiber as the tunable time delay. This system offers advantages of high bandwidth and tunability over current methods of time delay filtering. The method uses a single length of high dispersion fiber to achieve a variable time delay. By tuning the wavelength the relative time delay is changed. For a 1 km length of high dispersion fiber (-98 ps/km-nm) approximately 5ns of delay has been demonstrated over a 50 nm tuning range.
