title: Ultrahigh-order mode-assisted determination of enantiomeric excess in chiral liquids.
abstract: A chiral liquid, whose constituent molecules lack mirror symmetry, exhibits a minor differential refractive index (RI) between the two circular polarization components. Theoretical analysis shows that the ultrahigh-order modes excited in a symmetrical metal-cladding waveguide (SMCW) are polarization-independent and have a highly sensitive response to the RI variation. We report the observation of circular differential reflectivity in a chiral liquid-filled SMCW and propose an alternative simple technique capable of determining enantiomeric excess with high sensitivity.
