    In a single-mode optical fiber with a 10-μm-diameter core, a high-refractive-index rod is placed a distance S away in the cladding; the rod itself supports a mode, in addition to the mode supported by the core (a). The idea is for the rod to couple resonantly to the core, drawing light in certain spectral regions away from the core and absorbing it, thus serving as a spectral filter. The width of the peak bandwidth narrowed as the rod was moved farther from the core (b).
    A single-mode silica fiber has a high-refractive-index rod placed in the cladding that resonates with the core, absorbing light at certain wavelengths.

    FIGURE 1. A full-wave finite-element analysis is done of electromagnetic waves that scatter off a metallic sphere. The electric-field variations make it necessary to use a fine mesh throughout the computational domain. As a consequence of the Nyquist-Shannon sampling theorem, each wavelength needs to be resolved with a minimum of two sampling points to avoid aliasing. In practice, this leads to a requirement of at least a handful of finite elements per wavelength in each spatial direction.
    Optics-modeling electromagnetics software beats the Nyquist criterion while saving computation time.
