Performance Evaluation of Linearly Chirp Fiber Bragg Grating for Time Delay Analysis in Beam Steering for Enhance Communication

The literature shows that the analysis of photonic true time delay lines (TTDLs) using fiber Bragg grating in beam-steering system for phase array antennas (PAAs). A specific value of microwave frequency (f
mw
) and no of antenna (N) will provide the optimized value of delay line for PAA. A specific number of linearly chirped fibers Bragg gratings (LCFBGs) are chosen to form the delay line. We conduct a parametric analysis of LCFBG, and the simulation study of an FBG built with length 80000 μm and Gaussian apodization yields a temporal delay of 674.79 ps across its reflecting spectrum bandwidth (4nm).Here, we present simulation results from OptiGrating version 4.2.2
