Acoustic control on refractive index of periodic nanostructures facilitate a colocalize far-reaching control of light propagation. Static tuning of photonic band gap in lithium niobate and silicon dioxide based one dimensional superlattice through the GHz plate wave perturbation is reported. Acoustic field confinement in proposed structure produces field pattern of mechanical strain, analysed for...
The performance parameter of a surface plasmon resonance sensor having silicon carbide as an additional layer is theoretically investigated. Using the transfer matrix method, the reflectivity and performance parameter in terms of sensitivity, detection accuracy and quality parameter have been calculated. To understand the dependency of sensitivity and detection accuracy in the proposed sensor, the...
The occurrence of a photonic band gap modulation in the periodic arrangement of a Si-SiO2 layer, in the presence of in-plane acoustic plate symmetric modes is studied. The proposed structure shows simultaneous existence of photonic band gaps in the infrared region and phononic band gaps in the GHz frequency range. Due to the presence of photonic band gaps and phononic band gaps, this arrangement is...
