Organic Conjugated Polymer with Strong, Ultrafast Response to Laser Light

Organic conjugated polymer with a strong, ultrafast response to laser light in the telecommunication wavelength range has been demonstrated.

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. Net results: Higher bandwidths & processing speeds in fiber optic systems. Lower power use. Greater ease of fabrication. Higher performance and more affordable information technology for consumers and national defense.

How does this polymer compare? New polymer shows n2 = 9.4 x 10-4 cm2/GW versus the standard semiconductor GaAs with n2 = 4 x 10-4 cm2/GW . Over twice the index means less than 1/4 the power consumption.
