Speech Title: Optical fiber gratings for sensor and laser applications
Abstract: In past two decades, optical fiber gratings have received considerable research and application interests. They are periodic or quasi-periodic refractive index modulation structures created inside optical fiber with various laser sources such as UV lasers and femtosecond lasers. Optical fiber gratings are usually classified into two different types according to period sizes- short-period gratings (or fiber Bragg gratings) and long-period gratings. They can serve as excellent in-fiber mirrors or filters in fiber lasers. In sensing applications, they can be used to measure various physical parameters. In this paper, we will review our past and recent research work on optical fiber gratings and discuss their applications in fiber lasers and sensors.
