Abstract
We investigate the modal characteristics of solid-core Bragg fibers with complex refractive index profiles using Galerkin’s
method under the scalar linearly polarized (LP) mode approximation. The imaginary part of the electric field results in wavefront
distortion which is critically dependent on the imaginary part of the refractive index. The optical gain is calculated for
three physically acceptable values of the imaginary part of the refractive index. As the operation wavelength increases, the
gain decreases because the optical power confined to the core decreases.
