Análise de amplificação Raman em fibras microestruturadas de baixa perda
(Universidade Presbiteriana Mackenzie, 2008-02-13)
This dissertation aims to describe the basic characteristics of microstructured fibers, their concept and performance, and to investigate the application of a low loss microstructured fiber to the development of Raman ...
Um novo esquema de proteção para redes PON TDM
(Universidade Presbiteriana Mackenzie, 2008-08-06)
By adopting a ring topology and optical switches we propose a novel protection mechanism for time division multiplexed passive optical network (TDM-PON) that provides resilience against multiple network fails. Some protection ...
Geração e propagação de pulsos em laser a fibra dopada com Érbio com cavidades ultralongas
(Universidade Presbiteriana Mackenzie, 2012-11-01)
We investigated the mechanisms responsible for pulse formation and evolution in Erbium-doped fiber lasers with cavity lengths varying from 16.4 m to 100.8 km that were actively mode-locked at repetition rate of 1 GHz. The ...
Dispositivos fotônicos a partir da micromanipulação das propriedades de fibras ópticas
(Universidade Presbiteriana Mackenzie, 2015-08-26)
This thesis describes the development of new photonic devices produced by micromanipulation of the optical fibers properties, i.e., the change, in the micrometer scale, of the fiber s optical and/or geometrical properties. ...
