RT info:eu-repo/semantics/article T1 Hermetic carbon coatings for electro-thermal all-fiber phase modulators A1 García Ruiz, Andrés A1 Fidalgo Martins, Hugo A1 Teixeira Magalhaes, Regina Manuela A1 Pereira, João A1 Tarasenko, Oleksandr A1 Norin, Lars A1 Margulis, Walter A1 Martín López, Sonia A1 González Herráez, Miguel K1 Carbon K1 Electrothermal effects K1 Optical fiber protective covering K1 Optical time domain reflectometry K1 Phase modulation K1 Rayleigh scattering K1 Electrónica K1 Electronics AB Joule effect and thermal response of several carbon-coated fibers are modelled and analysed. An electro-thermally driven all-fiber phase modulator based on these principles is proposed and a proof of concept of it is characterized. This kind of fibers could be the basis for developing all-fiber components aimed to operate in environments where the strength increase and impermeability to hydrogen diffusion guaranteed by the carbon coating is crucial.
