Abstract
We present a photonic feed-forward radio-frequency filter with all-optical tunability. The filter incorporates a novel wavelength-selective true time delay in a delay-line-canceler architecture. We demonstrate tuning of the filter null frequency by changing the wavelength of the optical carrier. Application of this technique in optically controlled radars is discussed.Keywords
