Nonlinear competition heats up: four materials that transform light in unusual ways are going head to head in the race to build the fastest devices - such as switches - for optical communications systems

Article Abstract:

Researchers are excited about the race to find the best nonlinear optical materials (NLO) for applications in optical communications systems. NLO polymers make better electro-magnetic modulators than do inorganic crystals. Glass fibers and semiconductor NLOs make good all-optical switches.

Throwing - or molding - a curve into nanofabrication

Article Abstract:

Researchers have developed a method for using an elastomeric master for pattern molding to produce patterned optical surfaces. The micromolding technique creates gratings hundreds of nanometer wide on both flat and curved optical material.

Nonlinear molecules trip the light

Article Abstract:

Researchers have developed polymers that enhance the third-order nonlinear optical effect through molecular manipulation. The discovery could lead to the development of all-optical switches for fiber-optic communication systems.
