Opals in a New Light
Article Abstract:
Artificial opals are increasingly used in carbon structures to produce photonic crystals and macroporous materials. The artificial opals, or colloidal crystals, because of their 3D regularity are proving invaluable in photonic applications. The improvements of optical devices may depend to a great extent on photonic crystals.

Bunches of Photons--Antibunches of Electrons
Article Abstract:
A laboratory version of the Hanbury Brown and Twiss experiment demonstrates that the photons that make up the light beam are bosons that tend to bunch in clusters. Two studies that indicate that replacing the bosons with fermionic particles such as electrons results in antibunching are described.

Playing Tricks with Light
Article Abstract:
It is now theoretically possible to make photons interact with one another according to the latest advances in photon research. It was found that photonic insulators and materials with a photonic band gap can help control and exploit light. This theory is discussed.
