Study of the Chalcogenide Nonlinear Fiber Bragg Gratings for All-Optical Switching

Communications, 2012
In this paper uniform and apodized nonlinear chalcogenide glass fiber Bragg gratings (FBG) as novel and promising devices for all-optical switching are investigated. The transmission response of these devices is discussed theoretically.
