The survey considered additional information on more than 130 companies such as data on intellectual property, community service and financial growth trends. Readers were also asked five distinct questions, including the following:
- Where would you like to work based on their R&D?
- What companies have the most improved R&D in the past five years?
- What companies are the leaders in R&D?
- Which company's R&D has the strongest influence on society?
- Which company's R&D is the most proactive in high tech challenges?
Take for example IBM's recent breakthrough in Silicon photonics. Supercomputers that consist of thousands of individual processing nodes, typically running Linux on dual-core or quad-core processors, connected by miles of copper wires could one day fit into a laptop PC. And while today’s supercomputers can use the equivalent energy required to power hundreds of homes, these future tiny supercomputers-on-a-chip would expend the energy of a light bulb, so this solution is more "green" for the environment.According to the [IBM Press Release]:
The breakthrough -- known in the industry as a silicon Mach-Zehnder electro-optic modulator -- performs the function of converting electrical signals into pulses of light. The IBM modulator is 100 to 1,000 times smaller in size compared to previously demonstrated modulators of its kind, paving the way for many such devices and eventually complete optical routing networks to be integrated onto a single chip. This could significantly reduce cost, energy and heat while increasing communications bandwidth between the cores more than a hundred times over wired chips.
“Work is underway within IBM and in the industry to pack many more computing cores on a single chip, but today’s on-chip communications technology would overheat and be far too slow to handle that increase in workload,” said Dr. T.C. Chen, vice president, Science and Technology, IBM Research. “What we have done is a significant step toward building a vastly smaller and more power-efficient way to connect those cores, in a way that nobody has done before.”
Today, one of the most advanced chips in the world -- IBM’s Cell processor which powers the Sony Playstation 3 -- contains nine cores on a single chip. The new technology aims to enable a power-efficient method to connect hundreds or thousands of cores together on a tiny chip by eliminating the wires required to connect them. Using light instead of wires to send information between the cores can be 100 times faster and use 10 times less power than wires.

I can't wait for that laptop!
