- Ring-resonator-based frequency-domain optical activity measurements of a chiral liquidFrank Vollmer
The Rowland Institute at Harvard, Harvard University, Cambridge, Massachusetts 02142, USA
Opt Lett 31:453-5. 2006..The effect is in principle not diminished if the circumference of the ring is reduced. The technique is similarly applicable to refractive index and linear birefringence measurements...
- Single virus detection from the reactive shift of a whispering-gallery modeF Vollmer
The Rowland Institute, Harvard University, Cambridge, MA 02142, USA
Proc Natl Acad Sci U S A 105:20701-4. 2008..By comparing the electromagnetic theory for this reactive effect with experiments, the size and mass ( approximately 5.2 x 10(-16) g) of a bound virion are determined directly from the optimal resonance shift...
