HERNANDEZ-GARCIA, J.C. et al. Instrumentación y diseño de una fuente de alto voltaje para fabricar rejillas de fibra óptica mediante la técnica de arco eléctrico. Rev. mex. fis. [online]. 2010, vol.56, n.3, pp.255-261. ISSN 0035-001X.

In this work we present the instrumentation and construction of a source of high voltage, the source is controlled by the communication port Input/Output of a card of acquisition of data, we used programming language LabView®, is a tool for the design of acquisition systems, instrumentation and control. The source was utilize for to fabricate long period grating of optical fibers by means of inducing an electric arc with the point by point procedure, with this source is have low cost in the fabrication, this is 80 % down of technique with others devices. The instrument has a panel of virtual control to modify the time of duration of the arch, the voltage and the electric current applied to the optic fiber by means of two electrodes. The gratings were fabricated with SMF-28. These gratings can be used with optical fiber lasers as optical filters and in the implementation of optical sensors.

Palavras-chave : High voltage source; optical fibers; fiber optic gratings.
