[EN] We report experimental evidence of light guiding at telecommunication wavelengths along line-defect honeycomb-lattice photonic crystal waveguides created in suspended silicon slabs. Numerical results show that the ...
El objetivo de la tesis es es procesado de señales en las bandas de microondas y terahercios mediante dispositivos ópticos operando en la banda de comunicaciones. El procesado mediante tecnología convencional presenta una ...
Simultaneous self-collimation of sound beams with different frequencies, corresponding to fundamental wave and to its second harmonic, is proposed theoretically and demonstrated experimentally. The result is obtained when ...
[EN] The use of Spatial Division Multiplexing for Microwave Photonics signal processing is proposed and experimentally demonstrated, for the first time to our knowledge, based on the selective inscription of Bragg gratings ...
The main topic of this Final Grade Work is the evaluation, analysis and development of photonic technologies for the detection and physical-chemical characterization of particles that are present in multi-phase air-water ...
