Performance Analysis of U-FBG Fiber System using different Sizes of Bragg Cell

In practical applications, the Uniform fiber Bragg grating (UFBG) is a key component of integrated photonic circuits like optical filter, splitters, optical sensor and switches etc. This paper evaluates the performance of U-FBG fiber system by changing the size of Bragg cell based on Surface plasmon polaritons (SPP) using silver (Ag) profile material by Finite Difference Time domain (FDTD) method. It is observed that the maximum received optical power at the output port achieved is 8.48x 10 w/m with 0.9 μm radius of bragg cell and Silver (Ag) profile material at 0.8 w/m input transmission power whereas at 1.2 μm radius of bragg cell have low output power of 7.56x10 w/m .
