THE PROPAGATION MODES OF 2D PHOTONIC CRYSTAL WAVEGUIDE USED IN COUPLING BETWEEN CONVENTIONAL DIELECTRIC WAVEGUIDES

摘要

We studied the propagation modes of a two-dimensional photonic crystal waveguide and a problem of coupling between conventional dielectric waveguides, using the Fourier series expansion method combined with the absorbing boundary condition of a perfectly matched layer (PML). It is expected to explain the reason of the coupling efficiency between the photonic crystal waveguide and conventional dielectric waveguides.
