The Measurement of Nanoparticle Concentrations by the Method of Microcavity Mode Broadening Rate

A measurement system for the detection of a low concentration of nanoparticles based on optical microcavities with whispering-gallery modes (WGMs) is developed and investigated. A novel method based on the WGM broadening allows us to increase the precision of concentration measurements up to 0.005 p...
