Research output: Chapter in Book/Report/Conference proceedingConference contribution


We demonstrate pH sensing by using a silica toroid microcavity coated with 20-PAA/PAH multilayers, with a sensitivity of 0.14 pH. We also demonstrated the packaging of a tapered fiber and a microcavity in a liquid channel.
