| Objective:
Improve processibility, increase nonlinearity and reduce near-IR loss in highly conjugated systems.
|
Impact:
Materials with optical properties that vary rapidly and strongly with light intensity will enable future technologies that use light to control the flow of light. Such technologies will provide much higher bandwidths & processing speeds in fiber optic systems than today. Net result: Higher performance & more affordable information technology for consumers & national defense. |
How does this polymer compare?
Poly(RCOT) shows ultrafast
x(3) = 1.0 x 10-10 esu at 1300 nm, over twice that of the standard semiconductor GaAs. Diffraction efficiency of 0.14% exceeds Year 3 goal (0.1%).
