Photonic Crystal Fibers

Journal of Lightwave Technology, 2003
Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air holes that run along the entire fiber length. Largely through their ability to overcome the limitations of conventional fiber optics—for example, by permitting low-loss guidance of light in a hollow core—these fibers are proving to have a multitude of ...

Butterfly‐Inspired Tri‐State Photonic Crystal Composite Film for Multilevel Information Encryption and Anti‐Counterfeiting

Advances in Materials, 2023
Counterfeiting is a worldwide issue and has long troubled legitimate businesses, while nowadays anti‐counterfeiting materials and technology are still insufficient to combat the escalating counterfeit behaviors.

Impedance of photonic crystals and photonic crystal waveguides

Applied Physics Letters, 2004
We develop and demonstrate the concept of impedance for a photonic crystal by generalizing the transverse wave impedance of conventional waveguides. The impedance involves a ratio of transverse fields and power flux. The calculated impedance for a two-dimensional photonic crystal is very well defined using the transfer matrix method.
