Silicon nanophotonic chip has extraordinary optical effects, and now the technology is paving its way to impact our society. The IBM Photonic and Nanoscale systems Team has pushed the limits of fabrication and detection to sense ultra-small traces of methane released to our atmosphere. Tune in to this webinar hosted by the OSA Nanophotonics Technical Group to discover the transformation of a brilliant idea to a technology that is believed to perform reliable detection of pollutants in the atmosphere.

Tunable laser trace-gas spectroscopy has been effectively used in both environmental and medical applications, for its sensitivity and specificity. This webinar will feature a presentation from William Green of the IBM Thomas J. Watson Research Center describing how contemporary silicon photonics manufacturing and assembly can be leveraged for a cost-effective miniaturized spectroscopic sensor platform, and will outline uses in fugitive methane emissions monitoring.
