Abstract: En este trabajo nosotros estudiamos las propiedades de transmisión y Absorción de un sistema multicapa cuasiregular dieléctrico-grafeno-dieléctrico. La estructura multicapa está construida en base a una secuencia cuasi-regular Period-Doubling (PD). La respuesta óptica de el grafeno toma en cuenta las transiciones intra-banda e inter-banda. Nosotros usamos el método de matriz de transferencia para calcular los espectros de transmisión y absorción. Esto mostró una fuerte dependencia con el número de capas de sistema, el espesor de los medios dieléctricos y el contraste óptico. Además nosotros calculamos los espectros para la polarización transversal Magnética (TM) y transversal eléctrica (TE) en la región de frecuencia del infrarojo.
Description: Graphene is a two dimensional material of special interest due to its unusual electronic, mechanical, chemical, optical among other properties, which suggest a wide range of applications in optoelectronics, computer, ecology, etc. The study of the optical properties of graphene is important due to its potential applications such as ultrafast photonics, optical filters, composite materials, photovoltaics and energy storage device. In this work we study the transmission and absorption properties of a quasi-regular multilayer dielectric-graphene- dielectric system. The multilayer structure is built on the quasi-regular Period-Doubling (PD) sequence. The optical response of graphene takes into account intra-band and inter-band transitions. We use the transfer-matrix method to calculate the transmission and absorption spectra. It is obtained a strong dependence on the number of layers in the system, the width of dielectric media and the optical contrast. Furthermore, we calculate the spectra for both transverse magnetic (TM) and transverse electric (TE) polarization in the infrared region.
