Influence of the Wavelength on the Bandwidth in W-Type Plastic Optical Fibers

Abstract

We investigate the bandwidth and steady-state losses of multimode W-type plastic optical fibers solving the time-dependent power flow equation and show how the bandwidth in W-type plastic optical fibers can be enhanced by increasing the wavelength for different widths of the intermediate layer and refractive indices of the outer cladding. Such characterization of the fibers is consistent with their manifested efficiency in reducing modal dispersion and increasing bandwidth; this fact facilitates tailoring W-fibers to a specific application at hand at different wavelengths
