Modes of coupled photonic crystal waveguides.
We consider the modes of coupled photonic crystal waveguides. We find that the fundamental modes of these structures can be either even or odd, in contrast with the behavior in coupled conventional waveguides, in which the fundamental mode is always even. We explain this finding using an asymptotic model that is valid for long wavelengths.
متن کاملNonlinear Localized Modes In Photonic Crystal Waveguides
E xamples of the most significant recent research in optics and engineering are published each year in the December issue of OPN. This issue is comprised of short descriptions of the "hottest" topics in current optics research. Selection criteria applied to submissions are as follows: • the accomplishments described must have been published in a refereed journal in the year prior to publication...
متن کاملLow-loss guided modes in photonic crystal waveguides.
We study disorder-induced propagation losses of guided modes in photonic crystal slabs with line-defects. These losses are treated within a theoretical model of size disorder for the etched holes in the otherwise periodic photonic lattice. Comparisons are provided with state-of-the-art experimental data, both in membrane and Silicon-on-Insulator (SOI) structures, in which propagation losses are...
متن کاملNanopillars photonic crystal waveguides.
We present a novel type of a waveguide, which consists of several rows of periodically placed dielectric cylinders. In such a nanopillars photonic crystal waveguide, light confinement is due to the total internal reflection, while guided modes dispersion is strongly affected by waveguide periodicity. Nanopillars waveguide is multimode, where a number of modes is equal to the number of rows buil...
متن کاملPhotonic Crystal Nanocavities and Waveguides
Fabrication of optical structures has evolved to a precision which allows us to control light within etched nanostructures. Nano-optic cavities can be used for efficient and flexible concentration of light in small volumes, and control over both emission wavelength and frequency. Conversely, if a· periodic pattern is defined in the top semitransparent metal layer by lithography, it is possible ...
