“…Por tanto, podemos encontrarlos en una (1D), dos (2D) y tres (3D) dimensiones. Entre los materiales utilizados para construir estos cristales son los dieléctricos [4], semiconductores [5], superconductores [6], nanocompuestos [7], etc. Estas estructuras fueron estudiadas por primera vez en 1887 por Lord Rayleigh, quien descubrió que la propagación de la luz en medios estratificados unidimensionales puede ser totalmente reflejada dependiendo del ángulo de incidencia [8].…”

En este trabajo calculamos la dependencia de la sensibilidad de cinco células cancerígenas con el ángulo incidente de la radiación en un cristal fotónico unidimensional. El estudio se realizó para dos tipos de polarización: Transversal Eléctrica (TE) y Transversal Magnética (TM). Las muestras de las células se infiltran mediante biopsia líquida dentro de una nano cavidad que funciona como recipiente, y es revestida por nanocompuestos formados por la mezcla de la sílice con nano partículas de plata de tal forma que rompe la periodicidad del cristal fotónico compuesto por capas de SiO2 y aire. Encontramos picos de resonancia en el espectro de transmisión que caracteriza a cada célula infiltrada, por ende, este mecanismo de detección permite que el cristal fotónico funcione como un biosensor. Mediante el método de la matriz de trasferencia, para la polarización TE se observó un incremento de la sensibilidad al aumentar el ángulo incidente. Sin embargo, en la polarización TM no existieron aumentos significativos. Adicionalmente, se varía el espesor de la nano cavidad y el factor de relleno para obtener una mayor optimización. Los resultados revelan un incremento en la sensibilidad al aumentar el espesor de la nanocavidad, mientras que al aumentar el factor de relleno la sensibilidad decrece.

For the improvement of daily needs, the use of many chemicals is growing rapidly. Some of these compounds are harmful to human health. Moreover, due to the wide range of applications in industry, it has become necessary to develop rapid and accurate detectors for chemical compounds. Herein, a new chemical photonic structure is theoretically investigated as a detector for isopropanol, ethanol, and acetone. The proposed sensor is based on a 1D ternary photonic crystal and has the structure (Si/Si3N4/SiO2)N/cavity layer/(Si/Si3N4/SiO2)N. The organic chemical compounds are assumed to be separately infiltrated into the cavity layer. The defect layer (DLR) thickness, incident angle, number of unit cells, and the contrast between the high‐ and low‐index layers are varied and the sensitivity and quality factor are found for each case. The sensitivity can be considerably improved by increasing the DLR thickness, angle of incidence, and the contrast between the high‐ and low‐index materials. An extremely high sensitivity (2270.48, 2283.0555, and 2283.75) and quality factor (21.82 × 105, 21.48 × 105 and 21.46 × 105) are obtained for isopropanol, ethanol, and acetone. The results described earlier may pave the way for a practical and useful method of diagnosing chemical compounds.

“…PCs are usually of great interest due to their photonic band-gaps (PBGs) that stop the transmitted light in some particular frequency regions. Utilizing the unconventional substances such as metamaterial, superconductor, semiconductor [5], plasma [6,7], liquid crystal [8], etc. obviates the drawbacks of conventional PCs.…”

This study investigates the propagating of electromagnetic waves through a one-dimensional quasi-photonic crystal with the transfer matrix method. Our proposed structure consists of two types of double negative metamaterials, organized according to the Thue-Morse sequence law. The results show that changing the structure via quasi-periodic arrangements makes the outcome more varied than applying the absolute periodic arrangement. Given that, our desirable results of interest are more conveniently achieved. The structure completely stops-both s and p polarization at the lower frequencies, for all incidence angles. It also partially stops s and p polarization, at higher frequencies. Moreover, the achieved transmittance spectrum contains several omnidirectional band-gaps, which remain invariant with changes in the incidence angle. The oscillation of the transmittance values also becomes more intense at higher orders of the period number. This study could pave the way for optimizing of photonic crystal circuits, splitters, switches, etc.
