Resumo: | In this contribution we compare the thermal tuning capabilities of two type I gratings, considering an unloaded and a hydrogen-loaded fiber, and a type IIa grating. We further study their responses stability with temperature, analyzing their potential as optical filters in wavelength division multiplexing systems. We conclude that all of them have similar tuning efficiencies, however, as the temperature is changed, the type I grating written in the unloaded fiber presents much higher variations on its reflectivity, bandwidth and group delay than the other two cases, misadvising its utilization as thermo-tunable optical filter for wavelength-multiplexed systems. The best tuning range/filter response variation balance is achieved for type IIa gratings. |

Estudamos a estabilidade das respostas com a temperatura, analisando o seu potencial como filtros ópticos em sistemas com multiplexagem no comprimento de onda. Conclui-se que todas elas têm eficiências de sintonia semelhantes, contudo, à medida que varia a temperatura, as redes do tipo I em fibras não hidrogenizadas apresentam maiores variações na reflectividade, largura de banda e atraso de grupo, do que os outros dois casos, desaconselhando a sua utilização como filtro termosintonizável em sistemas com multiplexagem no comprimento de onda. O melhor balanço gama de sintonia/variação da resposta do filtro é conseguida para as redes do tipo IIa.UA Editora2002-01-01T00:00:00Zjournal articleinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://proa.ua.pt/index.php/revdeti/article/view/17886oai:proa.ua.pt:article/17886Eletrónica e Telecomunicações; Vol 3 No 7 (2002); 625-627Eletrónica e Telecomunicações; vol. 3 n.º 7 (2002); 625-6272182-97721645-0493reponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAPenghttps://proa.ua.pt/index.php/revdeti/article/view/17886https://proa.ua.pt/index.php/revdeti/article/view/17886/12837https://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/openAccessLima, M.
