The experiment used a telecoms wavelength probe laser that was coupled to a silicon nitride photonic integrated circuit using a fibre array. We excited the photothermal effect in the water vapor above the micro-ring using a 1395 nm diode laser. We measured the 1f and 2f wavelength modulation response versus excitation laser wavelength and verified the power scaling behaviour of the signal.<\/jats:p>","DOI":"10.3390\/s24113679","type":"journal-article","created":{"date-parts":[[2024,6,6]],"date-time":"2024-06-06T06:40:26Z","timestamp":1717656026000},"page":"3679","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Micro-Ring Resonator Assisted Photothermal Spectroscopy of Water Vapor"],"prefix":"10.3390","volume":"24","author":[{"given":"Maria V.","family":"Kotlyar","sequence":"first","affiliation":[{"name":"Centre for Advanced Photonics and Process Analysis, Munster Technological University, Bishopstown, T12 P928 Cork, Ireland"},{"name":"Tyndall National Institute, Dyke Parade, T12 PX46 Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-5398-5283","authenticated-orcid":false,"given":"Jenitta Johnson","family":"Mapranathukaran","sequence":"additional","affiliation":[{"name":"Centre for Advanced Photonics and Process Analysis, Munster Technological University, Bishopstown, T12 P928 Cork, Ireland"},{"name":"Tyndall National Institute, Dyke Parade, T12 PX46 Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriele","family":"Biagi","sequence":"additional","affiliation":[{"name":"Centre for Advanced Photonics and Process Analysis, Munster Technological University, Bishopstown, T12 P928 Cork, Ireland"},{"name":"Tyndall National Institute, Dyke Parade, T12 PX46 Cork, Ireland"},{"name":"PolySense Lab, Dipartimento Interateneo di Fisica, University and Politecnico of Bari, Via Amendola 173, 70126 Bari, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anton","family":"Walsh","sequence":"additional","affiliation":[{"name":"Centre for Advanced Photonics and Process Analysis, Munster Technological University, Bishopstown, T12 P928 Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3838-5842","authenticated-orcid":false,"given":"Bernhard","family":"Lendl","sequence":"additional","affiliation":[{"name":"Institute of Chemical Technologies and Analytics, TU Wien, Getreidemarkt 9\/164, 1060 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liam","family":"O\u2019Faolain","sequence":"additional","affiliation":[{"name":"Centre for Advanced Photonics and Process Analysis, Munster Technological University, Bishopstown, T12 P928 Cork, Ireland"},{"name":"Tyndall National Institute, Dyke Parade, T12 PX46 Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,6,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1300","DOI":"10.1016\/j.jqsrt.2011.11.008","article-title":"Pho-tonic sensing of the atmosphere by absorption spectroscopy","volume":"113","author":"Cui","year":"2012","journal-title":"J.
