“…In the one of the experimental work [30], The authors experimentally investigated 1D photonic crystals fabricated by etching air trenches into AlGaAs slab waveguides. In the other work [31], experimentally reported that the gas of the oxygen (O 2 ) is elaborated by PECVD technique in a One-dimensional photonic crystal. We can also use the same techniques to apply rubidium gas as a defect layer.…”

We investigate the steady-state and dynamic behavior of the optical properties of the laser pulse in a GaAs/AlAs 1D photonic crystal (1DPC) with an atomic vapor defect layer. We chose the atomic vapor of the 87Rb as a defect layer by driving the probe field on the D2 transition between 52P3/2 - 52S1/2 levels through the 1DPC. The effect of the photonic bandgap (PBG) on the absorption and dispersion properties of the probe field is discussed. Moreover, the transmission and reflection coefficient of the 1DPC is controlled by applying the various value of the intensity of the coupling field. By comparing these results in the vacuum and near the PBG, we find that the absorption/dispersion and transmission/reflection properties are strongly affected by the PBG. We find that all-optical properties of atomic vapor in the surrounding of 1DPC are improved due to PBG. Furthermore, the effect of the intensity of the coupling field on the all-optical switching is studded. The proposed model may provide some new possibilities for technological applications as an all-optical device based on the photonic crystal in quantum information science, quantum computing, signal processing, and quantum communications.

“…Отдельно стоит отметить возможность создания оптических фотонных кристаллов на их основе. Наличие запрещенных зон в области длины волны видимого света открывает широкие возможности по управлению и контролю над ним [11,15,17]. Таким образом, в настоящее время существует значительный запрос на технологию синтеза высокоупорядоченных надмолекулярных 3D-структур, обладающих значительным (> 1 мм 3 ) пространственным совершенством упаковки монодисперсных (отклонение частиц от среднего размера < 5 %) сферических частиц в интервале от 100 до 800 нм.…”

The paper considers the problem of instability of tetraethoxysilane hydrolysis in an ethanol medium in the presence of ammonia as a catalyst to obtain monodisperse spherical silica particles of a given size. This problem is associated with the presence of various impurities affecting rate of particle formation and, as a consequence, their size, monodispersity and shape. To solve this problem, we present novel studies of possible application of ultrafiltration for hydrolysis of initial tetraethoxysilane and ethanol through hydrophobic filters with a pore size of 50 nm. In both cases, we noted a decreasing intensity of light scattering after filtration. The elemental analysis of filtered impurities showed a significant content of SiO2 solid phases in tetraethoxysilane, and a number of impurities in ethanol. The experiments on the synthesis of silica particles from pre-filtered components showed that the resulting silica particles had a greater degree of monodispersity, and their sizes were much more reproducible, regardless of the used tetraethoxysilane. Thus, according to the obtained data, ultrafiltration is one of the effective ways to solve the problem of instability in the synthesis of monodisperse spherical silica particles.
