Firm touts electro-optic silicon replacement

April 18, 2006 – PSI-Tec Corp. says it has successfully tested an engineered organic material with a molecular electro-optic coefficient approximately twice that of other organic electro-optic materials used to convert electronic signals into optical signals for telecom and navigational systems, and possibly eventually optical interconnects and all-optical transistors.

The new structure, called “Perkamine-NR,” has molecules with approximately 15% reduced physical length, over competitive “CLD/FTC-base class” high-performance electro-optic organic molecules, developed primarily by DARPA, the U. of Washington, Lumera Corp., and Lockheed Martin, the company said, citing research by C.C.Teng, creator of electro-optical analytical techniques, and its own scientists. They said the Perkamine material has a molecular electro-optic coefficient approximately twice that of two electro-optical materials, DR1 and CLD-1, at fiber-optic wavelength 1300nm in standard PMMA guest-host films. Ron Genova, interim CEO of PSI-TEC Corp., noted that the results “were obtained from a disciplined, repeatable, low-cost commercial manufacturing process.”

The company said its new material has been shown to be able to exploit either “second-order” electro-optic nonlinear-optic (NLO) effects, for future applications in high-speed Internet, telecom, satellite, and military applications — or “third-order” effects where one beam of light is used to control another, allowing for future applications in all-optical transistors and switches.
