Mathematical modeling of the optical response from addressed fiber Bragg structure based on Lorentz function

Abstract

The paper discusses mathematical modeling of the optical spectrum of the addressed fiber Bragg structure. The approach uses Lorentz function to describe the spectrum of the transparency window of the addressed structure with two symmetrical π-phase shifts. The approach allowed to define the influence of the width of transparency window on the amplitude and the full width at half maximum of the address frequency spectral component. The obtained relations can be used to estimate the bandwidth of the electric bandpass filters necessary for signal detection, as well as the desired level of optical power of the light source.
