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.

Photonic Crystals with a Defect Fabricated by Two-Photon Polymerization for the Infrared Spectral Range

open access: yesOptics, 2021
One-dimensional photonic crystals composed of alternating layers with high- and low-density were fabricated using two-photon polymerization from a single photosensitive polymer for the infrared spectral range. By introducing single high-density layers to

Highly efficient coupling between a monolithically integrated photonic crystal cavity and a bus waveguide [PDF]

open access: yes, 2012
We experimentally demonstrate a new optical filter design comprising of a photonic crystal cavity and a low index bus waveguide which are monolithically integrated on a silicon-on-insulator (SOI) platform.

Design and characterisation of photonic quasicrystals from microwave to optical regime [PDF]

open access: yes, 2010
Photonic band-gap materials are artificially periodic engineered materials with which we can control and manipulate the electromagnetic radiation. The period photonic crystals are well known and have been studied for the last two decades.
