The Early Photon Gets the Worm

By Ken Tichauer | Posted: 25 April 2014

One of the biggest problems with using light to analyze biological tissue is that photons in the visible and near-visible spectrum have a very high probability of scattering multiple times as they propagate through the tissue. This is a well-known problem that restricts high-resolution optical microscopy to tissue thicknesses of only a few microns. It has also led researchers to develop complicated iterative reconstruction algorithms that incorporate models of scattering light propagation as a means of achieving usable image resolution in thicker tissue samples or in small animals. Even so, the ultimate resolution of these reconstruction algorithms is on the order of millimeters, far from the impressive micron and sub-micron scale resolution achievable by microscopy.

So the question is, what if we could tell the difference between photons that took a direct route through the tissue (non-scattering photons) and photons that took a more roundabout route (scattering photons)?

Silicon Photonics: Present & Future Perspective at IPR

By Shamsul Arafin | Posted: 28 June 2013

III-V/silicon hybrid lasers, silicon-itself lasers and III-V/silicon photonic integrated circuits (PIC) - in general, silicon photonics is the research area moving forward at a great speed over the last couple of years. Why such a great speed? Because a number of ever-demanding applications like optical interconnects, long haul communication systems, and conventional CMOS technology need added bandwidth, which could be easily realized by this growing research area. In addition, currently researchers are thinking about the integration of the silicon laser into chips that could be used for medical and security applications.

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?
