Simple prism-based scheme for fabricating Bragg gratings in optical fibers

Abstract

A modified prism-based method for fabricating Bragg gratings in optical fibers is introduced. We have made an optical fiber Bragg grating at 799.67 nm by using a 45 degrees right-angle prism and a frequency-doubled argon-ion laser at 244 nm. The advantage of this method is ease of alignment.
