Paper Abstract

Whispering gallery mode resonators provide a robust and sensitive platform for the trace detection of chemical and/or biological analytes. The conventional approaches exhibit some challenges in simultaneous multi-channel (i.e., multi-species) detection. We will present an alternative monitoring scheme that allows for the spatial multiplexing of whispering gallery mode resonators with the simultaneous observation of the resonance spectra from each of them. The resonance spectra and corresponding shifts due to analyte adsorption are readily observed from different spherical resonators.
