Abstract

COVID-19 pandemic is calling for new methods of remote chemical sensing, which can potentially detect small number of viral particles in air at safe distances. Raman spectroscopy is a chemically specific spectroscopic technique; however, it is often difficult to apply it for remote sensing due to the non-directional scattering. We propose and demonstrate a novel way to achieve directional backward emission through nonlinear Raman interactions.
