Higher levels of integration are required in planar lightwave circuits (PLCs) to lower costs and increase functionality in smaller footprint. Many different approaches using conventional waveguides (CWGs) and photonic crystal (PhC) structures have been proposed to meet such demands. CWGs are attractive due to low propagation loss, low coupling loss to and from fiber, and low dispersion. However the large radius of curvature required for high efficiency bends limits the possible level of integration in PLCs. Alternatively, PhCs have received much attention due to their capability to manipulate light propagation in a compact region. However, high propagation loss and coupling loss from and to fiber are problematic issues for PhC structures.Subjects--Topical Terms:

520 $a Higher levels of integration are required in planar lightwave circuits (PLCs) to lower costs and increase functionality in smaller footprint. Many different approaches using conventional waveguides (CWGs) and photonic crystal (PhC) structures have been proposed to meet such demands. CWGs are attractive due to low propagation loss, low coupling loss to and from fiber, and low dispersion. However the large radius of curvature required for high efficiency bends limits the possible level of integration in PLCs. Alternatively, PhCs have received much attention due to their capability to manipulate light propagation in a compact region. However, high propagation loss and coupling loss from and to fiber are problematic issues for PhC structures.
520 $a In this dissertation, I examine the combination of PhCs and CWGs in hybrid structures that leverage the advantages of each approach. Hybrid structures consist of CWGs for the low loss transport of light integrated with PhC regions of very limited spatial extent to dramatically reduce the size of waveguide devices. This preserves the traditional advantages of CWGs while advantageously using the attractive properties of PhCs.
520 $a Ultracompact high efficiency 90 degree bends, splitters, and a polarizing beam splitter using hybrid PhC and CWG structures are numerically designed and analyzed. Wave vector diagrams have been used to understand hybrid PhC and CWG structures. For some cases, diffraction at the periodic boundary surface of PhC limits the maximum 90 degree bend efficiencies. A micro genetic algorithm (muGA) combined with 2-D finite difference time domain (FDTD) method is used to effectively suppress undesired diffraction by manipulating parameters of the PhC region and the periodic boundary layer which in turn maximizes the bend efficiency. A compact Mach-Zender interferometer and ring resonators are designed by combining ultracompact high efficiency hybrid PhC and CWG 90 degree bend and splitter structures. The proposed Mach-Zender interferometer and ring resonator show attractive performance characteristics and design flexibilities.
