Paper Abstract

We demonstrate a wavelength- and bandwidth-tunable reflective filter based on a novel fiber Bragg grating chirping technique. The new technique allows grating to be chirped in a wide range without center Bragg wavelength shift. The tunabilities of the new band reflective filter are based on the responses of the grating pitch to the temperature and the applied strain gradient. It enables wavelength and bandwidth tuning ranges up to 5.2 nm and 10.9 nm, respectively.
