cone can be used to create optical waveguides on printed circuit boards that can withstand extreme operat- ing heat and humidity with no meas- urable degradation in performance. The materials can be fabricated into waveguides using conventional man- ufacturing techniques that are avail- able today. Board-level waveguides will help
pave the way for the low-cost integra- tion of photonics in energy-efficient supercomputers and data centers. With exabytes of structured and
unstructured data growing annually at 60 percent, scientists have been researching a range of technological advancements to drastically reduce

route electrical signals,” explains Dr. Bert Jan Offrein, manager of the Photonics Research Group at IBM Research. “Our design is highly flex- ible, resistant to high temperatures and has strong adhesion properties; these waveguides were designed with no compromises.” In a collaboration with Dow
Corning, the scientists for the first time fabricated thin sheets of optical waveguide that show no curling and can bend to a 1mm radius and is sta- ble at extreme operating conditions in- cluding 85 percent humidity and 85°C. This new polymer, based on silicone materials, offers an optimized combi-
