The coupling dependence between a wire waveguide and a two-dimensional photonic
crystal waveguide on a shared connection structure was analyzed theoretically. By …

Coupling between conventional wire waveguide and two-dimensional photonic crystal
waveguide was analyzed by means of a three-dimensional finite difference time domain …

As one of the key component of photonic crystal optical circuit devices, the directional
coupler is investigated. We explain the reason the directional coupler consisting of an …

We have demonstrated 1.55 μm wavelength lightwave propagation through a 120° sharply
bent waveguide formed in a triangular-lattice two-dimensional photonic crystal (2D PC) …

We demonstrate a method to create a highly confined waveguide with sharp bend in three-
dimensional photonic crystal. By theoretical calculation, we show that a single-mode …

In this paper, wide-bandwidth low cross-talk W1 photonic crystal waveguide intersections
are proposed based on self-collimation effect. The waveguides are realized using a 2D …

We propose an approach to construct waveguide intersections with broad bandwidth and
low cross-talk for square-lattice photonic crystals, by utilizing a vanishing overlap of the …

The behavior of two nearby straight photonic crystal waveguides is analyzed. It is shown that
the two guides, considered as a single system, may realize a very efficient wavelength …

In the last decade, there has been an extensive interest in the properties of photonic crystals,
which are artificial periodic structures of dielectric composites. In photonic crystals, the …

Optical properties of a straight 50-row-long photonic crystal waveguide (PCW) are reported.
This waveguide is obtained by removing one row of air holes in a triangular lattice two …
