By using a Fourier processor based on the temporal Talbot effect and the properties of the Discrete Fourier Transform, we propose a scheme that adds an adjustable delay to a train of pulses while simultaneously preserving the clock recovery property of the Talbot effect. The obtained delay can be easily tuned by modifying only the electrical signal applied to an electro-optic modulator. Experimental results prove the validity of the proposal with a fine correspondence between the desired and measured delays all over a complete period of the signal., This work was supported in part by the Ministerio de Economia y Competitividad of Spain under Grant TEC2014-58048-C2-1-P and Grant TEC2014-58048-C2-2-P

This work presents an experimental demonstration of a scheme based on an internally modulated fiber ring laser for high-sensitivity temperature sensing. The attained temperature resolution has been as low as ± 2pm even when a commercial FBG with a sensitivity of 10 pm/°C was used. Thus, a fivefold improvement in the temperature sensor resolution can be achieved when compared to a simple FBG interrogation scheme. In addition to this, the measuring range could be selected only by changing the frequency modulation of the fiber ring laser. This technology also allows to triple the photodiode bandwidth unambiguously when temperature or strain measurements are carried out, which is a remarkable achievement in term of cost reduction., This work was supported by the Spanish Government projects TEC2013-47264-C2-2-R and TEC2014-58048-C2-1-P.
