Yet the path toward an even faster internet has been hindered by energy consumption and cost per optical component, said Wei Shi, Assistant Professor, Université Laval in Québec, Canada.
Shi and his colleagues have designed a tunable filter -- an important component of high-capacity optical networks -- that should save both money and energy because it can be readily integrated onto a photonic chip. The device's performance is comparable to the best bench-top systems, but at a fraction of the size and cost. The filter's tuning span, which is a measure of how well the device can adjust to fluctuating data demands, is the widest ever demonstrated on a silicon chip. Additionally, the device has an unlimited free-spectral range, meaning it can operate over any range of frequencies, and shows excellent performance metrics in other standard measures of filter quality, including very low insertion loss and in-band ripples, low crosstalk and small delay variation. "The most exciting aspect is that these record-breaking results were achieved on the silicon photonic platform," Shi said. "Compared to traditional networks where optical resource allocations are predetermined and fixed, flexible networks enable orders-of-magnitude higher data volumes per optical carrier and throughout the entire spectrum," Shi said. Flexible networks require tunable filters. Filters isolate a specific communication channel from all the others and tunable filters give a network controller the freedom to select the frequency and bandwidth for each channel and change them on the fly. The tunable filter that Shi and his colleagues designed and tested has a tuning span of 670 GHz, much greater than the approximately 100 GHz span other silicon-based filters have achieved. "Higher capacity optical networks affect consumers in a big way," Shi said. The next-generation of internet technology could mean videos that stream in 3D or 360 degrees and vast amounts of cheap cloud data storage. "Think about the improvements to internet services in the past 10 years," Shi added.

Ju-Chin Huang of the University of New Hampshire and her students, Wei Shi (a PhD student) and Christin Badylak-Reals (an undergraduate at UNH), are preparing questionnaires that we will be mailing and handing out to local residents and beach-goers about the natural and human changes on Plum Island.
