Realization of Attenuator and Amplifier Using Photonic Crystal Fiber

Abstract

The present paper realises the attenuator and amplifier of electromagnetic signals with silicon-based, square-type photonic crystal fiber. In this research, the input signal varies from 30 eV to 30,000 eV, which lies within the x-ray regime. The operational mechanism deals with the electric field distribution in the structure, which is carried out using the plane wave expansion technique. The numerical outcomes affirm that the increasing and decreasing amplitudes of incident signals occur at the output end of the fiber. The intrinsic mechanism of such an interesting result is nonlinear properties of field distribution at a different value of lattice spacing and the diameter of the proposed fiber's air holes. Finally, the immediate upshot's outcome resembles the amplifier and attenuator about the optical system.
