“…A sub-micrometer optical structuring of the nanocomposites significantly expands the field of their possible applications. Periodic structures based on the nanocomposites can be used as holographic diffractive optical elements (DOE) for light control or for displays [ 12 , 17 ], as DOE with ultrahigh spectral dispersion [ 20 , 21 ], and as distributed feedback cavities of waveguide lasers [ 22 , 23 ]. In 2010, the concept of using periodic structures based on the nanocomposites for neutron optics was proposed and successfully implemented [ 12 , 24 ].…”

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.

“…In the past two decades, organic solid-state lasers (OSSLs) 1 2 3 4 5 6 7 8 9 10 11 12 13 have been developed extensively because of the easy fabrication of laser devices by spin-coating or solution casting, the low cost of device fabrication, and the wide variation of the lasing wavelength, ranging from the visible to near infrared regions, that can be selected depending on the laser dye used. Slope efficiency is an important measure to evaluate the performance of the laser devices.…”

Organic solid-state lasers (OSSLs) with distributed feedback structures can detect nanoscale materials and therefore offer an attractive sensing platform for biological and medical applications. Here we investigate the lasing characteristics, i.e., the threshold and slope efficiency, as a function of the grating depth in OSSL devices with distributed feedback (DFB) structure fabricated using photoresists. Two types of photoresists were used for the DFB structures: a negative photoresist, SU-8 2002, and a positive photoresist, ma-P 1275. The DFB structure was fabricated using a Lloyd-mirror configuration. The active layer was a rhodamine 6G-doped cellulose acetate waveguide. The threshold for the first order mode (m = 1) was lower than that for the second and third order modes (m = 2, and 3). A low threshold of 27 μJ cm−2 pulse−1 (58 nJ) was obtained using SU-8 2002, with m = 1. The slope efficiency was evaluated as a function of grating depth for each mode and increased as the grating depth increased.

“…Knowing the propagation constants in a waveguide, and corresponding fields, enables us to calculate gain coefficients of active laser media, binding coefficients between modes, and also to explain characteristics of similar multilayer waveguide lasers with Bragg gratings [3]. The calculated fields show that they approach their maximum value in layers with a higher refractive index.…”

“…However, modern integrated optics uses complex multilayer waveguides, for example, semiconductor lasers with double heterostructure, consists of five layers, and each layer has its own refractive index [2]. Distributed feedback waveguide microlaser, based on organic semiconductors has 3 or 4 layers [3,4]. Increasing the number of layers complicates the transcendental equation and, therefore, its solution.…”

Abstract. Possibilities of new numerical method for solving the wave equation of multilayer planar waveguide were investigated. The method is based on the use of Fourier transform to the wave equation and its solution in the frequency domain by using the numerical method. The final task of finding propagation constants and the Fourier images of the fields in discrete form is reduced to the problem on the eigenvalues and eigenvectors. The new method provides highly accurate calculation of propagation constants and their fields and is characterized by high numerical stability.
