photodetector 40Gig Edit

* An anonymous reader writes "Intel has developed a device, the Avalanche Photodetector, that [0]senses light pulses and amplifies output signals for faster data transfer over long distances. Researchers claim this is a big advancement in the field of silicon photonics, in which silicon is used to transfer light pulses for data exchange between chips and devices. APD can detect light at higher frequencies and moves data at rates of 40Gbps, making it more sensitive and quicker than earlier photodetectors, at a tenth the cost."

Besides use in optical computer and communications links, technology based on the new device could be used to make highly sensitive infrared imaging systems and cameras. It could also be used to create more sensitive biochips or better fibre-to-the-home components. - CctvCameras

As anyone who has tried to route a board with a large number of GHz I/Os knows all too well, it would be wonderful to have direct optical interconnect between ICs. The potential bandwidth would be large, the signal integrity issues minimal, and perhaps the power much lower. But there is one huge problem: the technologies necessary to illuminate an optical channel, modulate it and convert the optical signal back into an electrical one are all big, expensive, and incompatible with standard CMOS processes. This is a problem on which Intel researchers have been toiling for some time. And earlier this week, they announced another incremental step toward a complete solution: an avalanche photodetector that is in principle compatible with silicon CMOS processes.
