## Abstract We experimentally demonstrate a novel tunable microwave notch filter using a fiber loop and cascaded fiber Bragg gratings (FBGs), where the filter response can be easily tuned by adjusting the wavelength of the input light. The proposed notch filter is very simple to realize. The requir
EDFA preamplified recei¨ers can achie¨e sensiti¨ities close to those possible with heterodyne detection while offering a simplified system design. For this sensiti¨ity benefit to be realized, narrow optical bandpass filters are needed to limit the EDFA amplified spontaneous ( ) emission ASE noise. T
