1. A new technique for interrogating fiber optic sensors with Bragg gratings / Uma nova tecnica para interrogação de sensores a fibra otica com grades de Bragg
The recent advances in fiber optics and eletronic circuits has led to the development of many sensors based on fiber optics, with a great emphasis on Fiber Bragg Gratings (FGB) sensors. The FGBs sensors are used to quantify severeal measurands, as temperature, pressure, tension, thermodynamics and electrical current, with good accuracy and resolution. In thi

2. Métodos sintéticos para preparação de 2,2'-bipiridinas substituídas
The 2,2'-bipyridine has been entitled as the most widely used ligand. Nowadays there is a large variety of known molecules comprising at least two 2,2'-bipyridine units and the number of applications in many areas such as catalysis, new materials, optoeletronics and electrochemistry have increased very much in the past decades. Nevertheless, there is no arti

3. REFLECTOMETRIA COERENTE APLICADA AO ESTUDO DA INSTABILIDADE DE FREQÜÊNCIA E EFEITOS TÉRMICOS EM LASERS DE REALIMENTAÇÃO DISTRIBUÍDA / STUDY OF FREQUENCY INSTABILITY AND THERMAL EFFECTS IN DISTRIBUTAL FEEDBACK LASERS WITH COHERENT REFLECTOMETRY
Coherente reflectometry has been an important technique for characterization of optinal and optoeletronics devices used in communications systems. In this work, Coherente frequency domain reflectometry was used in the study of the Distributed-Feedback Semiconductor lasers characteristics. The measurement of thermal response of the laser module, linearity of
