Holographic mirrors act as optical switches

An Israeli company, with researchers at the California Institute of Technology and the Hebrew University of Jerusalem, has reported the development of electrically charged holographic images within crystals capable of selectively reflecting specific wavelengths of light. Trellis Photonics says that the technology will switch data faster than existing optical-electrical switches and is more accurate. The breakthrough holds the promise of significantly increasing Network speeds as, currently, the conversion of optical to electrical for switching purposes is a significant bottleneck in throughput.
