“…Tailoring light absorption and emission with use of engi neered nanophotonic structures (photonic crystals, metamat erials and etc) is an active area of research due to its potential applications, as in: miniature lasers and light emitting diodes [1][2][3]; singlephoton generation; quantum information [4][5][6][7]; controlling light propagation [8]; accumulation of solar energy [9][10][11][12][13]; sensing; integrated photonics [13][14][15][16][17][18][19][20][21][22][23][24], etc.…”

We investigated peculiarities of absorption, emission and photonic density of states of a cholesteric liquid crystal with an isotropic defect inside. The influence of the defect position on absorption and emission in the system was studied. It is shown that for non-diffracting circularly polarized incident light absorption/emission is maximum if the defect is in the centre of the system; and for diffracting circularly polarized incident light absorption/emission is maximum if the defect is shifted from the centre of the system to its left border from where light is incident. We also investigated influence of the defect layer thickness and those parameters which characterize absorption and gain on absorption and emission. The influence of anisotropic absorption in the cholesteric liquid crystal layer on photonic states of density was investigated, too.

“…Photonic crystals (PC) are periodical optical micro-and nanostructures that receive increasing attention due to their ability to manipulate light propagation while maintaining high transmission efficiency[13]. If electromagnetic waves propagate into the photonic crystal structure, then the waves will be scattered due to differences in the refractive index in the structure.…”

The optical response of the photonic crystal structure has been analyzed using the Finite Difference Frequency Domain (FDFD) method. Simulation using this method aims to analyze the characteristics of light transmission when interacting with related structure. The results of the study of photonic crystal structures with two defects show that there are two transmittance bands called double resonances at two specific wavelengths. Changes in the resonance peak with respect to the variations of refractive index in the second defect layer resulted in a linear change with significant sensitivity. For photonic crystals with two defects, the first defect is a metal layer and the second defect is material sensing, which produces double resonance with a sensitivity of 7,825 and 3,2675, while for photonic crystals with the first defect, a dielectric layer, and the second defect is material sensing, produces single resonance with a sensitivity of 2,022. The choice of the first defect is that the metal layer is quite important, in addition to producing greater sensitivity, it also produces a field enhancement between the dielectric and the metal layer which is called surface plasmon resonance (SPR). The sensitivity value can also be set by determining the thickness of the second defect layer. These results can be used as a standard for fabrication and developed for sensor applications.
