Abstract

By using a beam of uniform strength, bi directional chirp free tuning of center wavelengths of the fiber grating is realized, and the tuning range up to 12.52 nm is obtained. The experimental results accord well with the theoretical analyses. The beam of uniform strength is simple in configuration, low cost and is easy to be operated. It has been used in our homemade tunable fiber lasers, sensors and add/drop multiplexers etc..
