## 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

Abstract
A tunable fiber Bragg grating (FBG) filter with a tuning resolution of less than one picometer (pm) is demonstrated. The FBG is embedded in carbonβfiber composite material, which is bent by using a simple mechanical setup. A tuning range of 2 nm and repeatability of less than 0.4% are obtained.

## Abstract This study describes a wavelengthβtunable fiber laser based on a broadband fiber mirror and an etched fiber Bragg grating (FBG) with a tuning range exceeding 15 nm. The experimental results indicate that this configuration provides a simple and economical method of implementing a wavele
## Abstract The use of a linear magnetic actuator for the tuning of a fiber Bragg grating filter is demonstrated. Experimental results show that the tuning repeatability is better than 1.4% within a 2βnm tuning range. Β© 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 33, 73β74, 2002; Publis
This paper reports on a Q-switched Er-doped fiber laser using the stress dependence of a wavelength of reflected light from fiber Bragg gratings. The laser cavity consists of a 0.5-m-long Er-doped fiber and two fiber gratings (FG) attached at both ends of the fiber. The pump laser is a 1.48 mm semic
## Abstract Chromatic dispersion effect on a bandpass microwave photonic filter is presented using a tunable linearly chirped fiber Bragg grating (LCFBG). The 3βdB bandwidth of the LCFBG is shifted nonlinearly with fixed centre wavelength to change its chromatic dispersion value. The bandpass notch
## Abstract We propose an experimental realization of flatβtop filters by fabricating fiber Bragg gratings in gradedβindex multimode fibers (GIβMMF). Two types of GIβMMFs were used to make this kind of filters, and their spectra and polarization properties were experimentally investigated. Β© 2007 W
