The diversity of three-dimensional photonic crystals

open access: yesNature Communications, 2021
Photonic crystals have a range of desirable properties for manipulating light. Here, the authors calculate and use the photonic band gap for thousands of such crystals to examine heuristics for their design and predict new photonic crystal structures.

Hollow core photonic bandgap fibers for telecommunications: opportunities and potential issues [PDF]

open access: yes, 2012
We discuss the potential advantages that hollow core photonic bandgap fibers may ultimately have over conventional all solid fibers and review the state-of-the-art, fundamental physical limits and the many technological challenges to be ...

Photonic band-gap structures [PDF]

open access: yesJournal of the Optical Society of America B, 1993
The analogy between electromagnetic wave propagation in multidimensionally periodic structures and electron-wave propagation in real crystals has proven to be a fruitful one. Initial efforts were motivated by the prospect of a photonic band gap. a frequency band in three-dimensional dielectric structures in which electromagnetic waves are forbidden ...

Electroless plated maghemite for three-dimensional magneto photonic crystals

open access: yesAIP Advances, 2017
Three-dimensional magneto photonic crystals (3D-MPCs) are promising material for manipulating light in 3D space. In this study, we fabricated 3D-MPC that is filling the air-gap of opal photonic crystal with magnetic material by electroless plating.
