Attaching Fibers To Photonic Chips


Recently, Cadence held its fifth photonics summit, CadenceCONNECT: Photonics Contribution to High-Performance Computing. You can read my earlier posts: Photonic Integration—From Switching to Computing How to Design Photonics If You Don't Have a PhD: iPronics and Ayar Labs The third day was all about how to connect the incoming and outgoing fibers to the photonics chips. I will cov... » read more

System Bits: Sept. 3


Microprocessor built with carbon nanotubes Researchers at the Massachusetts Institute of Technology were able to design a microprocessor with carbon nanotubes and fabricate the chip with traditional processes, an advance that could be used in next-generation computers. Work on producing carbon nanotube field-effect transistors has gone on for some time. Fabricated at scale, those CNFETs oft... » read more

Power/Performance Bits: July 16


Bacterial solar Researchers at the University of British Columbia developed a solar cell that uses bacteria to convert light to energy. The cell worked as efficiently in dim light as in bright light, making solar a potential option in areas of the world that frequently have overcast skies. Called biogenic cells, they work by utilizing the natural dye that bacteria use for photosynthesis. Pr... » read more

Power/Performance Bits: Dec. 31


Approximate computing With the potential to double efficiency and reduce energy consumption, Purdue University and NEC Laboratories America researchers are developing computers capable of "approximate computing" to perform calculations good enough for certain tasks that don't require perfect accuracy. The need for approximate computing is driven by a fundamental shift in the nature of compu... » read more

Perfect ICs Are integrated circuits "too good" for current technological applications? Christian Enz, the new director of the Institute of Microengineering at Ecole Polytechnique Fédérale de Lausanne (EPFL) believes perfection is overrated. Enz said the reason why we should build our future devices with unreliable circuits, and adopt the "good enough engineering" trend is that non-fully r... » read more
