Optimization of Bistability in Nonlinear Chalcogenide Fiber Bragg Grating for All Optical Switch and Memory Applications
We solve the coupled mode equations governing the chalcogenide nonlinear fiber Bragg gratings (FBGs) numerically, and obtain the bistability characteristics. The characteristics of the chalcogenide nonlinear FBGs such as: switching threshold intensity, bistability interval and on-off switching ratio are studied. The effects of FBG length and its third order nonlinear refractive index on FBG cha...

متن کاملTheory of Fiber Optical Bragg Grating- Revisited
The reflected signature of an optical fiber Bragg grating is analyzed using the transfer function method. This approach is capable to cast all relevant quantities into proper places and provides a better physical understanding. The relationship between reflected signal, number of periods, index of refraction, and reflected wave phase is elucidated. The condition for which the maximum reflectivi...
متن کاملFiber-Bragg-Grating Based Optical Amplifiers
In this chapter, we propose several schemes for fiber amplifiers which are all using fiber Bragg gratings (FBGs) as the key elements for their advantages of better uniformity, higher contrast ratio and lower cost. Several applications using FBG-based fiber amplifiers are also introduced. Therefore, this chapter initiates the overview of FBGs characteristics in Sec. 1, then addresses the FBGs pl...
متن کاملDispersion Compensation in Optical Fiber Communication using Bragg Grating
This paper discussed on a simulation of optical transmission system in optical fiber. To achieve the foremost effective performance of communication system, dispersion should be stipendiary. Fiberbragg grating is chosen as important components to compensate the dispersion in optical communication system.FBG is very simple, has low cost filter for wavelength selection and low insertion loss, it ...
