Abstract: The tuning characteristics of the fiber Bragg gratings are analyzed on theory and experiment, and a tunable fiber Bragg grating device with a PZT has been realized, which can be tuned about 1.344 nm. Compared with other types of tunable fiber Bragg grating, this device has the advantages ofsimple structure, easy realization and stable performance. By the way, the tuning characteristics of the fiber Bragg grating are also studied when bending it inexperiment, and the tuning range is about 1.68 nm.

Key words: wavelength division multiplexing, fiber gratings, wavelength selection and tuning
