Highly dispersive photonic band-gap-edge optofluidic biosensors [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2006
Highly dispersive photonic band-gap-edge optofluidic biosensors are studied theoretically. We demonstrate that these structures are strongly sensitive to the refractive index of the liquid, which is used to tune dispersion of the photonic crystal.

Realization of a novel multimode waveguide with photonic band gap hopping based on coupled-resonator optical waveguide theory

open access: yesResults in Physics, 2023
Traditionally, in the application of photonic crystals, defect modes are mostly introduced in the photonic band gap to realize high-performance waveguides, and electromagnetic waves beyond the photonic band gap cannot be controlled in photonic crystals ...

Band gap of silicon photonic crystal with square-lattice and windmill-shaped defects

open access: yesResults in Physics, 2021
A new type of 2D square-lattice photonic crystal with different windmill-shaped defects is proposed. Based on the plane wave expansion method and super cell theory, the band gaps of defect models are numerically analyzed according to the symmetry. We aim

Effect of windmill-like-shaped defect on TM photonic band gaps of two-dimensional square-lattice photonic crystals

open access: yesResults in Physics, 2020
A novel windmill-like-shaped defect was introduced in two-dimensional square-lattice photonic crystals consisting of circular dielectric rods. The photonic band gap (PBG) and defect modes were numerically analyzed using the plane wave expansion method ...

Location and Topology of the Fundamental Gap in Photonic Crystals

open access: yesPhysical Review X, 2022
The fundamental, or first, band gap is of unmatched importance in the study of photonic crystals. Here, we address precisely where this gap can be opened in the band structure of three-dimensional photonic crystals.
