One Step

Previous discussions of mode coupling at a QT region have assumed vertical incidence and have hus invoked magnetic structures which violate div B = o. A new method is developed here for alculating the coupling coefficients for oblique incidence so that coupling at a QT region can be reated without invoking nonphysical magnetic structures. The method involves solving the Booker uartic equation implicitly in terms of the familiar formulae of magnetoionic theory. A coupling pproximation is introduced which involves one step in an iterative procedure to find explicit solutions rom the implicit ones. The approximation is necessarily valid in a finite range about the critical oupling points. The present method is used to generalize the results of Cohen to allow oblique ncidence. The results of the existing discussions of mode coupling for vertical incidence and nonphysical agnetic structures can be justified both qualitatively and semiquantitatively (although ith a slightly different physical interpretation).

The Finite Difference Method

Design of optical spectral filters based on mode coupling of optical fibers is presented. The finite difference method is applied to evaluate the dispersion characteristics of optical fiber coupler which is constructed from two fibers as a composite multi-dielectric waveguide with different cores but the same cladding. Also, power and field distributions for both fibers as a separate and as a composite waveguide are investigated. The spectral characteristics of the filters are computed depending on the coupling of two linear polarized modes LP01 and LP11. The dependence of the transmission coefficient on operating wavelengths is illustrated. Finally, the spectral bandwidth of filter as a function of the distance between the two cores is addressed.

Difference Time

In this paper, we propose and investigate an optical wavelength division multiplexer based on periodic dielectric waveguide ring resonator by using finite-difference time-domain method. From the simulation results, compact and high performance wavelength division multiplexer could be obtained to separate the wavelength of 1.31μm and 1.55μm.
