Frozen light

Article Abstract:

Electromagnetism is a mediator of all interactions i atomic physics, however Diederik Wiersma and colleagues have shown that light can be made to stand still by multiple scattering and wave interference. The discovery will lead to applications i optical data processing, laser physic and spectroscopy. Samples of the semiconductor gallium arsenide were ground to a fine powder, and in the experiment photons experienced strong interference effects, impeding diffusion.

Large-scale synthesis of a silicon photonic crystal with a complete three-dimensional bandgap near 1.5 micrometres

Article Abstract:

The description of single crystals of silicon inverse opal with a complete three-dimensional photonic bandgap centred on 1.46 micro-m is presented. These crystals were produced by growing silicon inside the voids of an opal template of close-packed silica spheres that are linked by small 'necks' arising during sintering.
