Abstract

A polarized photon-pairs heterodyne polarimetry is proposed in order to measure in an ultrasensitive manner the circular birefringence of a chiral medium via optical rotation detection. A balanced detector is integrated into this Polarimeter. Thus, shot-noise-limited detection by this Polarimeter can be achieved. Experimentally, the detection sensitivity for the circular birefringence of a glucose-water solution up to ∂ |n_r - n ₁| = 2 × 10^-11 at 10 mg/dL is verified. To our knowledge, this is the highest sensitivity ever measured of a chiral liquid solution based on single traveling sample cell geometry. Finally, when compared to a fiber loop ringresonator in the frequency domain for a chiral liquid, this Polarimeter shows an order of 10⁴ enhancement on the sensitivity of natural optical activity measurement.
