[EN] We theoretically investigate phonon-photon interaction in cavities created in a phoxonic crystal slab constituted by a two-dimensional (2D) square array of holes in a silicon membrane. The structure without defects ...

[ES] Las arritmias son una condición padecida por gran parte de la población, entre el 1.5% y el 5% de ella. Por ello, durante los últimos años, se han mejorado los métodos de diagnóstico médico, con el propósito de prevenir ...

[EN] We investigate the dispersion of phononic crystal waveguides formed by evanescent coupling of a chain of defect cavities and supporting slow-wave propagation. These coupled-resonator acoustic waveguides (CRAWs) are ...

[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 ...

[EN] The interaction of light and sound waves at the micro and nanoscale has attracted considerable interest in recent years. The main reason is that this interaction is responsible for a wide variety of intriguing physical ...

[EN] We demonstrate theoretically that photons and acoustic phonons can be simultaneously guided and slowed down in specially designed nanostructures. Phoxonic crystal waveguides presenting simultaneous phononic and photonic ...

[EN] We show a theoretical study that permits us to obtain the relationship between the coefficients of stimulated emission, spontaneous emission and absorption in indirect bandgap semiconductors, including multiphoton and ...
