Until now much of the investment on equipment to generate, transport and detect signals traveling through optical fiber has revolved around 1.55 micron (infrared) as the standard wavelength for telecommunications. Yet many critical new applications rely on other wavelengths (colors) for optical transmission that hitherto could not be generated, carried or received by today's standard equipment. Now, researchers at the University of California, San Diego have demonstrated a way to build on the dominant infrastructure rather than replace it -- by "translating" optical signals between the current infrared standard and a wide range of other bands of light.
