Resumo: Photonic biosensors have gained much attention recently due to their high sensitivity, low energy consumption and miniaturization capability; in the near future, these sensors will form the basis of the so-called Lab on a Chip: a device capable of performing accurate clinical analyzes in a single chip and in any location, being of great help in countries with few resources for disease detection. There are several configurations for biophotonic sensors ranging from fiber-optic based systems, waveguides, resonators, to nanoparticles and photonic crystals, to name a few. In spite of this great diversity, constituted by dielectric or metallic media, these devices can be classified in two broad categories: those that require previous mode coupling and those that do not. The purpose of this dissertation is to study the devices of the second category, focusing on the so-called quasi-guided modes, presenting the physical phenomena involved and the main tools used to evaluate their performances. Therefore, using numerical simulations, present a comparative study between dielectric and metallic systems. Finally, a dielectric based biosensor is proposed, aiming on obtaining the similar performances of devices based on metal.

Existem diversas configurações de sensores biofotônicos, variando desde sistemas baseados em fibras-óticas, guias de onda, ressonadores, até nanopartículas e cristais fotônicos, para nomear alguns. Apesar de sua grande diversidade, constituindo-se por meios dielétricos ou metálicos, esses dispositivos podem ser classificados, de modo geral, em duas categorias: os que requerem acoplamento prévio do modo e aquelas de não requerem. O intuito dessa dissertação é estudar esses dispositivos da segunda categoria, focando nos chamados modos quase-guiados, apresentando os fenômenos físicos envolvidos e as principais ferramentas de avaliação da sua performance. Portanto, utilizando de simulações numéricas, apresentar um estudo comparativo entre os sistemas dielétricos e metálicos. Por fim, propor um biosensor baseado em meio dielétrico, com objetivo de atingir rendimento similar aos dispositivos baseados em metais.Biblioteca Digitais de Teses e Dissertações da USPMartins, Emiliano RezendeSoares, Rodrigo Romão França2020-05-15info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttps://www.teses.usp.br/teses/disponiveis/18/18155/tde-12052023-100106/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2023-05-15T12:27:55Zoai:teses.usp.br:tde-12052023-100106Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212023-05-15T12:27:55Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false
