Mar. 21, 2009 ScienceDaily: New Organic Material May Speed Internet Access; Telecom Breakthrough Mimics The Settling Snow

The next time an overnight snow begins to fall, take two bricks and place them side by side a few inches apart in your yard. In the morning, the bricks will be covered with snow and barely discernible. The snowflakes will have filled every vacant space between and around the bricks. What you will see, says Ivan Biaggio, resembles a phenomenon that, when it occurs at the smallest of scales on an integrated optical circuit, could hasten the day when the Internet works at superfast speeds. Biaggio, an associate professor of physics at Lehigh University, is part of an international team of researchers that has developed an organic material with an unprecedented combination of high optical quality and strong ability to mediate light-light interaction and has engineered the integration of this material with silicon technology so it can be used in optical telecommunication devices.

March 16th, 2009 TopTenReviews: New Silicon-Organic Hybrid Material Could Make Internet Even Faster

The term “green” has become ubiquitous in politics and technology to describe efforts to lessen, prevent and even reverse environmental damage and unsustainable growth and energy consumption. Now, however, with scientists and engineers looking to nature for organic components to enhance and expand synthetic mechanisms, the term “green” has come full circle.

March 16, 2009 Lehigh University Press Release: Silicon-Organic-Hybrid Integrated Devices for All Optical Switching

Silicon-Organic-Hybrid Integrated Devices for All Optical Switching Our development of a high-quality supramolecular assembly of small molecules with a large third-order optical nonlinearity represents a new, flexible organic material for integrated nonlinear optics. One the best ways to control the propagation of a tightly focused optical mode in an organic material is not to build a waveguide using the material itself, but to combine the materail with silicon-waveguiding technology so that the silicon (transparent at telecommunication wavelengths!) will be responsible for controllilng the optical mode and its propagation, while the organic will be responsible for the nonlinear optical effects. Silicon processing technology has developed to the extent that millimeter-scale devices are routinely fabricated with nanometer precision in modern high-volume complementary metal oxide-semiconductor (CMOS) lines, making silicon-on-insulator (SOI) one of the most attractive platform for photonic circuits or integrated optics.

April 15, 2009 IMEC advance hints at all-optical add-drop multiplexers

As bit rates in the optical backbone speed past 40 Gbits/s per wavelength, there is a fundamental problem with the front-end optical-to-electronic conversion process. As Roel Baets, head of the photonics research group at IMEC, points out, you can do the optical-to-electronic conversion at 10 Gbits/s, and you can think of ways to do it at 40 Gbits/s. But to convert a single optical pulse train at over 40 Gbits/s to electronic pulses is a daunting prospect at the least. A better approach, were it possible, would be to demultiplex the bit stream optically, producing several lower-rate bit streams that could then be converted. Such a demultiplexer would require an optical switching device capable of synchronous operation at over 100 Gbits/s—something that had been heretofore only speculation. But a recently-described breakthrough at the University of Karlsruhe, in collaboration with IMEC, Lehigh University, and ETH Zurich, has demonstrated optical demultiplexing at these speeds.
