A Novel Fabrication Technique of Long Period Fiber Gratings
A Novel fabrication technique of long-period fiber gratings is proposed, which are fabricated with periodic modulation of the refractive index of the core by heating and tapering fiber with carved periodic V-grooves. The experimental results are presented, and their fundamental principle is analysed. The most common use of the long-period fiber gratings is as a broadband rejection filter for WDM systems.
