Stimulated Raman spectroscopy of analytes evanescently probed by a silicon nitride photonic integrated waveguide

We report, to the best of our knowledge, the first demonstration of stimulated Raman spectroscopy enhanced by a nanophotonic integrated circuit. The Raman response of low-concentration dimethyl sulfoxide is evanescently probed via centimeter-long wire waveguides. A signal enhancement of close to fiv...
