First Electronic Optical Fibers with Hydrogenated Amorphous Silicon are Developed (IMAGE)
Caption
A new chemical technique for depositing a non-crystalline form of silicon into the long, ultra-thin pores of optical fibers is the first of its kind to use high-pressure chemistry for making well-developed films and wires of this particular kind of silicon semiconductor. The research, led by John Badding at Penn State University, will help scientists to make more-efficient and more-flexible optical fibers. This image shows a bed of amorphous hydrogenated silicon wires that were prepared in the pores of optical fibers. The wires have been chemically etched out of the optical fiber to reveal them. Scale bar is 100 um. Inset: An array of amorphous hydrogenated silicon tubes deposited in an optical fiber. The optical fiber has been cleaved in half to reveal the array of tubes. The very thin glass walls of the fiber surrounding each tube are largely obscured.
