Simple microspheres working as Fabry\u2013Perot cavities are interrogated in reflection and in transmission. Two microspheres were also spliced together, and subjected to different physical parameters. These structures are an alternative solution for load measurement and, when read in transmission, it is also possible to apply strain. Moreover, the structure is capable of being used under extreme ambient temperatures up to 900 \u00b0C. Random signal in cleaved microspheres was demonstrated with the possibility of using it for random laser or sensing applications. All this work was developed at the Centre for Applied Photonics, INESC TEC.<\/jats:p>","DOI":"10.3390\/fib6030048","type":"journal-article","created":{"date-parts":[[2018,7,11]],"date-time":"2018-07-11T10:50:09Z","timestamp":1531306209000},"page":"48","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["A Brief Review of New Fiber Microsphere Geometries"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3512-3687","authenticated-orcid":false,"given":"Andr\u00e9 Delgado","family":"Gomes","sequence":"first","affiliation":[{"name":"Centre for Applied Photonics, Institute for Systems and Computer Engineering, Technology and Science (INESC TEC), 4169-007 Porto, Portugal"},{"name":"Department of Physics and Astronomy, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"},{"name":"Leibniz Institute of Photonic Technology, 07745 Jena, Germany"}]},{"given":"Catarina Silva","family":"Monteiro","sequence":"additional","affiliation":[{"name":"Centre for Applied Photonics, Institute for Systems and Computer Engineering, Technology and Science (INESC TEC), 4169-007 Porto, Portugal"},{"name":"Department of Physics and Astronomy, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8549-4051","authenticated-orcid":false,"given":"Beatriz","family":"Silveira","sequence":"additional","affiliation":[{"name":"Centre for Applied Photonics, Institute for Systems and Computer Engineering, Technology and Science (INESC TEC), 4169-007 Porto, Portugal"},{"name":"Leibniz Institute of Photonic Technology, 07745 Jena, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7680-1056","authenticated-orcid":false,"given":"Orlando","family":"Fraz\u00e3o","sequence":"additional","affiliation":[{"name":"Centre for Applied Photonics, Institute for Systems and Computer Engineering, Technology and Science (INESC TEC), 4169-007 Porto, Portugal"},{"name":"Department of Physics and Astronomy, Faculty of Sciences, University of Porto, 4169-007 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2018,7,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2756","DOI":"10.1063\/1.1662645","article-title":"Light coupling from a stripe-geometry GaAs diode laser into an optical fiber with spherical end","volume":"44","author":"Kato","year":"1973","journal-title":"J.
