INTEC, imec's associated lab at Ghent University, in collaboration with Columbia University and IBM TJ Watson Research Center (US), has demonstrated efficient up-conversion of mid-infrared signals into the telecom band by means of four-wave mixing in a Si optical waveguide. With this spectral translator, smaller, lighter and more highly integrated mid-infrared optical systems can be developed for a variety of applications. This work has recently been published in Nature Photonics.
The researchers used efficient four-wave mixing in silicon nanophotonic wires to enable spectral translation of a signal at 2,440nm to the telecom band at 1,620nm, across a span of 62THz.
