Novel applications of fiber Bragg grating components for next-generation WDM systems

The main purpose of this paper is to present an overview of novel applications enabled by major improvements realized in FBG technology. First, we will review the principle of operation of FBG-based components and the numerous recording techniques used to fabricate those types of components. We will next show that this technology combined with new innovative manufacturing process is well suited to overcome the challenges imposed on optical components for next-generation WDM systems.
