Paper Abstract

This paper focuses on introducing the results of a model using a control system for an optical filter that can be tuned, using a solution that employs both, an elongation control system and a fiber Bragg grating. At the first stage, the optical characterization of the filter was made, then the stepper motors were chosen for the desired wavelength selection with a couple of pulleys which produce the grating elongation and, as a consequence, the wavelength shifting. The pulleys diameters were calculated to produce 0.8 nm shift for each filtering wavelength using a control program.
