Bat algorithm (BA) is one of the recently proposed heuristic algorithms imitating the
echolocation behavior of bats to perform global optimization. The superior performance of …

Slow light in photonic crystal waveguide (PCW) is now being heavily investigated for
applications in optical devices. However, slow light with high group index in perfect PCW is …

Abstract Ring-Shape-Hole Photonic Crystal Waveguides (RSHPCW) is a popular structure
in designing optical buffers attracted many attentions recently. There are some parameters …

A high sensitive multi-component gas sensing system was proposed, in which the slotted
photonic crystal waveguide (SPCW) was used as the gas cell and the fiber Fabry–Perot …

We comprehensively calculated the photonic bands of the waveguide modes in practical
lattice-shifted photonic crystal waveguides, which are completely cladded by silica. We …

Photonic crystal waveguides are optimized for modal confinement and loss related to slow
light with high group index. A detailed comparison between optimized circular-hole based …

Light localization and intensity enhancement in a woodpile layer-by-layer photonic crystal,
whose interlayer distance along the light propagation direction is gradually varied, has been …

A photonic-crystal waveguide hosted in an annular photonic crystal is demonstrated
theoretically to realize polarization-independent slow light. Through an appropriate set of …

This paper proposes a new kind of photonic crystal waveguide (PCW) called asymmetric
oval-shaped-hole PCW (AOPCW). In this PCW, 20 structural parameters are considered …

By separating two photonic crystals with a distance of 2 3 a, where a is the lattice constant,
shifting the positions of some discriminatory air holes in the upper and lower edges, and …
