## Abstract Chromatic dispersion effect on a bandpass microwave photonic filter is presented using a tunable linearly chirped fiber Bragg grating (LCFBG). The 3‐dB bandwidth of the LCFBG is shifted nonlinearly with fixed centre wavelength to change its chromatic dispersion value. The bandpass notch

## Abstract A new technique for inducing relative group delays between the orthogonal transversal propagation modes in a single mode fiber is presented. It is based on a tunable linear chirp induced in a Bragg grating written in a highly birefringent fiber by thermal means. The method can induce a
## 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
## Abstract A Fabry‐Perot filter is realized by inscribing two identical 1 mm uniform Bragg gratings separated by 7.7 mm space in the hydrogen‐loaded photosensitive optical fiber. It is then incorporated with a tunable chirped fiber Bragg grating into a fiber ring cavity. Fourteen single‐wavelength
