## 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 o
## 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
