The eye of the peacock mantis shrimp has led an international team of researchers to develop a two-part waveplate that could improve CD, DVD, blu-ray and holographic technology, creating even higher definition and larger storage density. Peacock mantis shrimp are one of only a few animal species that can see circularly polarized light -- like the light used to create 3-D movies. Some researchers believe the mantis shrimp's eyes are better over the entire visual spectrum than any man-made...

Researchers in Britain and Denmark have unveiled an "Ëœinvisibility cloak' that uses a common crystalline material known as calcite, which works by sending its two "polarizations" of light in different directions. Cloaking involves guiding light waves in such a way that waves from a hidden object do not reach the eye.  By using calcite, the researchers created an "Ëœinvisibility cloak' that hid a small (inch-size), three-dimensional object.  However, the size of...

For many years, researchers have looked to develop organic materials as a reliable and cost effective replacement for inorganic materials in optical devices. The development of highly functionalized optical devices using photonics instead of optoelectronics has highlighted the need for greater control over the manipulation of optical signals. Photo-control of molecular orientation of polymer materials is of great interest for the development of highly functionalized holographic optical...
