“…The stable ordered structures are formed as a result of diffusion redistribution of the nanocomposite components upon polymerization in a spatially inhomogeneous light field [ 7 , 8 , 9 , 10 , 11 , 12 ]. The use of photopolymerizable nanocomposites allows the fabrication of one-, two-, and three-dimensional periodic structures of large size and high uniformity by a one-step method of holographic lithography, for example [ 13 , 14 , 15 , 16 ] and references therein. The holographic method also provides precise control over symmetry and periodicity of the structures.…”

Organic–inorganic photocurable nanocomposite materials are a topic of intensive research nowadays. The wide variety of materials and flexibility of their characteristics provide more freedom to design optical elements for light and neutron optics and holographic sensors. We propose a new strategy of nanocomposite application for fabricating resonant waveguide structures (RWS), whose working principle is based on optical waveguide resonance. Due to their resonant properties, RWS can be used as active tunable filters, refractive index (RI) sensors, near-field enhancers for spectroscopy, non-linear optics, etc. Our original photocurable organic–inorganic nanocomposite was used as a material for RWS. Unlike known waveguide structures with corrugated surfaces, we investigated the waveguide gratings with the volume modulation of the RI fabricated by a holographic method that enables large-size structures with high homogeneity. In order to produce thin photosensitive waveguide layers for their subsequent holographic structuring, a special compression method was developed. The resonant and sensing properties of new resonant structures were experimentally examined. The volume waveguide gratings demonstrate narrow resonant peaks with a bandwidth less than 0.012 nm. The Q-factor exceeds 50,000. The sensor based on waveguide volume grating provides detection of a minimal RI change of 1 × 10−4 RIU. Here we also present the new theoretical model that is used for analysis and design of developed RWS. Based on the proposed model, fairly simple analytical relationships between the parameters characterizing the sensor were obtained.

“…Together with the variation in the number of beams and the angles between them, it is also of interest to control the phase relationships between the interfering beams [29], which provides an additional capability to affect the resulting intensity distribution in the recording plane. In work [30], we proposed a modification to the recording scheme, in which a spatial light modulator is applied to form the interference pattern. In Fig.…”

Дослiджено властивостi об’ємних одно- та двовимiрних перiодичних структур, утворених наночастинками срiбла в полiмернiй матрицi. Особливiстю структур є те, що термо- або фотостимульований синтез наночастинок срiбла вiдбувається в полiмернiй матрицi з попередньо розподiленого методом голографiчної лiтографiї прекурсору металу. На основi просторового рiдкокристалiчного модулятора свiтла оптимiзовано схему багатопучкового голографiчного запису. Розглядаються механiзми формування перiодичних структур пiд дiєю iнтерференцiйного поля i синтезу наночастинок срiбла. Вивчається зв’язок спектральних властивостей отриманих структур з характеристиками наночастинок та їх просторовим розподiлом в полiмернiй матрицi.
