Amplificador Raman discreto para utilização em transmissão CWDM na banda O
(Universidade Presbiteriana Mackenzie, 2006-08-02)
Most of researches about Raman amplifier had been made in C and L bands (1530-1625 nm), which is possible to found more data of Raman efficiency gain and the requirements for design is consolidated. The first issue that ...
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 ...
Dissulfeto de molibdênio esfoliado micromecanicamente depositado em fibra óptica para geração de pulsos ultracurtos
(Universidade Presbiteriana Mackenzie, 2016-08-01)
In this work, we describe the characterization, transfer process and fabrication of mechanically exfoliated MoS2 (molybdenum disulfide) samples deposited on the fiber facet and D-shaped fiber. The characterization of ...
Moduladores de eletro-absorção integrados com materiais bidimensionais
(Universidade Presbiteriana Mackenzie, 2018-06-14)
Two-dimensional materials herald the coming of advances in many areas of Engineering, thanks to the peculiar physicochemical properties obtained when one isolates a single layer of minerals such as graphite and black ...
