It is shown that the selective excitation of linear polarized modes, during the fabrication process, has a direct impact on the shape of the resulting micro structures. Tips are fabricated with modes LP02 and LP21 and their shapes and output intensity distribution are compared. The application of the micro structures as optical tweezers is demonstrated with the manipulation of yeast cells.<\/jats:p>","DOI":"10.3390\/photonics2020634","type":"journal-article","created":{"date-parts":[[2015,6,12]],"date-time":"2015-06-12T10:56:00Z","timestamp":1434106560000},"page":"634-645","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Optical Fiber Tweezers Fabricated by Guided Wave  Photo-Polymerization"],"prefix":"10.3390","volume":"2","author":[{"given":"Rita","family":"Ribeiro","sequence":"first","affiliation":[{"name":"Faculdade de Ci\u00eancias da Universidade do Porto, Rua do Campo Alegre, 687. 4169-007 Porto, Portugal"},{"name":"INESC TEC, Rua do Campo Alegre, 687, 4169-007 Porto, Portugal"}]},{"given":"Raquel","family":"Queir\u00f3s","sequence":"additional","affiliation":[{"name":"INESC TEC, Rua do Campo Alegre, 687, 4169-007 Porto, Portugal"}]},{"given":"Olivier","family":"Soppera","sequence":"additional","affiliation":[{"name":"Institute de Science des Materiaux de Mulhouse, France CNRS UMR 7361, 68057 Mulhouse, France"}]},{"given":"Ariel","family":"Guerreiro","sequence":"additional","affiliation":[{"name":"Faculdade de Ci\u00eancias da Universidade do Porto, Rua do Campo Alegre, 687. 4169-007 Porto, Portugal"},{"name":"INESC TEC, Rua do Campo Alegre, 687, 4169-007 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1484-2068","authenticated-orcid":false,"given":"Pedro","family":"Jorge","sequence":"additional","affiliation":[{"name":"INESC TEC, Rua do Campo Alegre, 687, 4169-007 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2015,6,12]]},"reference":[{"key":"ref_1","first-page":"37","article-title":"Laser Processing by Using Diffractive Optical Laser Beam Shaping Technique","volume":"6","author":"Gedvilas","year":"2001","journal-title":"J.
