2013/11/26 50 Meters of Optical Fiber Shrunk to the Size of Microchips

I came across this article on the Facebook page for DARPA, The Defense Advanced Research Projects Agency.  I usually have about one half hour to read before I leave to go into work.  This is what I found today while having my morning cup of Earl Grey tea.  Here is an excerpt.

"DARPA's iPhoD program reaches successful conclusion with demonstration of low signal loss records with microchip-scale, integrated waveguides for photonic delay"

"DARPA's integrated Photonic Delay (iPhoD) program created a new class of photonic waveguides with losses approaching that of optical fiber. The new waveguides are built onto microchips and include up to 50 meters of coiled material that is used to delay light. Conventional fiber optic coils of the same length would be about the size of a small juice glass. These waveguides also employ modern silicon processing to achieve submicron precision and more efficient manufacturing. The result is a new component that is smaller and more precise than anything before in its class."
