Optical frequency comb generation using a microtoroid resonator in an aqueous environment

Abstract

Frequency locked optical microtoroid resonators can detect single molecules, however, they still require capture probes. Optical frequency combs in a microresonator can provide molecular spectroscopic information. Here we demonstrate generation of optical frequency combs using a microtoroid in air and water by achieving anomalous dispersion via intermodal coupling. We believe that this will enable single molecule detection and identification molecules without labels or capture probes.

Gwangho Choi received his B.S.E. from the Seoul National University of Science and Technology, South Korea, M.S. from the Rose-Hulman Institute of Technology, USA. He is currently pursuing a Ph.D. degree in College of Optical Sciences at the University of Arizona. His research interest covers characterization of an optical microresonator as well as either scientific or industrial applications of the resonator, such as bio-sensing and spectroscopy. His current research focuses on generating optical frequency combs in biological environments.
