A strong light-matter interaction is allowed, due to a strong photons confinement in the metal slot, which corresponds to a low mode volume (V = 2×10<sup>-3</sup> (λ/n)<sup>3</sup>). A Q-factor of 2.6×10<sup>3</sup> has been obtained, providing a ultra-high Q/V = 1.3×10<sup>6</sup> (λ/n)<sup>-3</sup>, with a resonance transmission of 48 % λ = 1563.70 nm. Accurate 3D Finite Element Method (FEM) simulations have been performed to design the cavity. Optical trapping has been identified as the most suitable application for the proposed device, due to a strong gradient of the light field in the metal slot that allows high values of optical force and, consequently, the ability to trap nanoparticle with a diameter less than 100 nm.","PeriodicalId":219746,"journal":{"name":"2014 Third Mediterranean Photonics Conference","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122276154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mode coupling within such fibers is a critical aspect of propagation, for it poses a limit to system capacity. In this paper we analyze fiber twist as a possible cause of mode coupling. It is shown that in a twisted fiber the LP modes undergo a rigid rotation proportional to the twist applied to the fiber. This rotation involves both mode power distribution and mode polarization, generalizing the well known polarization rotation (optical activity) that occurs in twisted single mode fibers. The results of this analysis may enable a more accurate modeling of propagation in randomly coupled multi- and few-mode fibers.","PeriodicalId":219746,"journal":{"name":"2014 Third Mediterranean Photonics Conference","volume":"99B 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128481554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A standard LPG is first transformed in a more practical probe working in reflection mode, then it is coated by a primary layer of aPS and a secondary layer of PMMA in order to increase its surrounding refractive index sensitivity and at the same time provide the necessary conditions for a correct bio-functionalization. Standard linkage chemistry has been applied to anchor the bioreceptors on the probe surface.
