Recently, the structure and various characterizations of nonlinear optical crystal
of morpholinium 4-aminobenzoate have been reported .
The light from the LED is cleverly diffused through frosted hand-ground optical crystal
which magnifies the light, creating warm pastel shades of colour.
Each piece is hand-cut and shaped out of optical crystal
glass; no molds of any kind are used.
Instead of bending and focusing light as it passes through a series of separate mirrors and lenses, the new folded system bends and focuses light while it is reflected back and forth inside a single 5-mm thick optical crystal
. The light is focused as if it were moving though a traditional lens system that is at least seven times thicker.
Tony Prew, who owns Crystalcraft, said: 'The brief is to steer clear of traditional trophies and deliver something modern and unique.' The team of the round trophies will be made of optical crystal
, which is engraved with the winning team's name and the LDV logo.
Steinberg, along with PhD students Kevin Resch and Jeff Lundeen, discovered the switch when they shone one strong beam and two weak beams of light on a special optical crystal
. When two photons -- one from each weak beam -- approached the crystal simultaneously, they collided and prevented each other from passing through, thereby switching each other off.
This recipe for an optical crystal
sounds simple, but preparing such a novel concoction requires considerable care.

Tokyo, Japan, Mar 29, 2007 - (JCN Newswire) - The Tokyo Institute of Technology and Fujitsu Laboratories Limited today announced their joint development of a new technology that enables the successful propagation of infrared light through an optical crystal
film on a silicon substrate, for the first time in the world.
