Photonics Integration and its future at Advanced Photonics 2013

By Shamsul Arafin | Posted: 19 March 2013

At the time of peak in technological development, isn’t it frustrating to hear that most of the computers used in our daily lives do nothing more than wait for the data? It is sad, but true, that your Intel® Core™ i5 Processor with high-speed RAM or state of the art liquid cooling system will not help you much to overcome this problem. This is because our computer speed is primarily set not by the processing power we have, but by the connections between the processor and the data it waits for. Photonics integration into the electronic circuits can resolve this problem easily because such photonic-electronic hybrid configuration can provide size weight and power reduction together with better system performance, e.g. speed, bandwidth and reliability. Not clear?

The point is that data transfer from module-to-module or chip-to-chip could be accomplished in a much efficient way with light or photons. This well-established fact motivates researchers worldwide to replace the existing old-fashioned copper wire technology to move the electronic signal by the photonics integration technique. Taking the fact – photons are much faster than electrons – into account and then developing an optical data transfer system, we’ll soon unveil computer systems 100 times (or even more!) faster than anything available today. If you cannot rely on me, I would request all of you to participate in Integrated Photonics Research, Silicon and Nano-photonics (IPR) 2013 meeting in OSA's Advanced Photonics Congress. Why?

Label-free imaging: What is it good for? Absolutely most things!

By Craig Goergen | Posted: 14 March 2013

Say it again! And while one of the plenary talks in the Opening General Session given by Sunny Xie (Monday, April 15th, 8:00 to 9:45am in the Ali’Ii Ballroom) titled "Label-Free Vibrational Imaging for Medicine" might be a little less funky, I am sure it will be equally as entertaining.

Dr. Xie is the Mallinckrodt Professor of Chemistry and Chemical Biology at Harvard University and is considered by many to be a founding father of the field of single-molecule enzymology. His group has also made significant contributions to the development of Coherent Anti-Stokes Raman Scattering (CARS - a dye-free method in which image structures are characterized by intrinsic vibrational contrast of their molecules). The advantage of this method is that it does not require labeling and the sample remains mostly unaffected.
