The introduction of defects in these ... A crystal with a 3-D photonic band gap is a powerful tool to control light, with applications for new types of solar cells, sensors and miniature lasers.

Photonic crystals are materials in which a periodic variation of the dielectric constant results in a photonic band gap. Photons with wavelengths or energies in this gap cannot travel through the ...

This periodic variation, in turn, produces a photonic “band gap” that affects how photons propagate through the crystal – similar to the way a periodic potential in semiconductors affects the flow of ...

Also known as photonic band-gap materials, photonic crystals are "tunable," which means they are precisely ordered to block certain wavelengths of light while letting others through. Alter the ...

Photonic crystals are optical materials with periodic changes in the dielectric constant on a length scale comparable to optical wavelengths. Dimensional types of photonic crystals, parallelism, ...

We developed a perturbation theory based on structural orientation angles to enable rapid calculation and adjustment of photonic band gaps. Since both pseudo-spin and valley lattices are ...

The team then confirmed the presence of a photonic band gap in the optical spectrum using optical photographs and transmission spectra (Nanotechnology 18 365601). The team found that the color of the ...

DUBLIN--(BUSINESS WIRE)--The "Advancements in Silicon Photonics, Wide Band Gap Semiconductors, and Displays" report has been added to ResearchAndMarkets.com's offering. This Microelectronics TOE ...

The two men finished lunch on amicable terms. They also agreed on a name for their idea: It should be called a photonic band gap. Their idea has since been realized in the form of photonic crystals, ...
