1. Amplificadores Ãpticos, estudos de polarizaÃÃo e geraÃÃo de pulso usando processos paramÃtricos em fibras Ãpticas
The recent telecommunication development can be, to a large extent, attributed to the capacity of transmitting information (video, sound and data) at high transmission rates (Tbits/s) through the optical fiber. The constant advances in the technological development of active and passive devices based on optical fibers have enabled a steady increase in commun

2. TÃcnicas de Interferometria Ãptica aplicada à medicina, odontologia e comunicaÃÃes Ãpticas
In the work described in this thesis, we used two different interferometric techniques, the coherent optical frequency domain reflectometry (COFDR), and the optical coherence tomography (OCT). Both techniques are based on the Michelson interferometer. They were applied to optical communications and to medical and dentistry imaging. We will give a general des

3. Amplificadores Ãpticos a fibras dopadas com TÃlio para a banda "S"
Due to the ever increasing amount of data traffic it has become necessary to expand the capacity of optical communication systems. This can be achieved by increasing the number of transmitted channels using Wavelength Division Multiplexing. Due to improvements of the manufacturing process of optical fibers, it is possible to use the entire low-loss spectral
