We fabricate a double-layer wire grid polarizer (WGP) and perform optical characterization to clarify the relationship between the structural and polarization characteristics. For normal incidence, the fabricated double-layer WGP exhibits an extinction ratio of 30.4 dB for a period of 400 nm. The transverse magnetic transmittance peak angle is found to vary with the period of the WGP. The peak shift can be explained on the basis of the extraordinary optical transmittance phenomena exhibited by the surface plasmon polaritons (SPPs) of metal slit structures according to the dispersion curve of the SPP. From the simulation of rigorous coupledwave analysis, it is considered that the incident light passes through the resist layer, followed by the excitation of SPPs at the interface between the resist and Au. Subsequently, the SPPs combine with the transmitted light in the glass substrate, leading to strong transmitted light with transverse magnetic polarization. Therefore, we demonstrate the extraordinary optical transmittance phenomena exhibited by the SPPs by both experiment and simulation.

“…Aso, it enables simple elements replication in order to form both spherical and aspherical wavefront sets, making diffractive optic's elements useful for different applications. The majority of studies consider diffractive optical elements either as additional elements for the compensation of aberrations of a refractive imaging system [4,5], or as elements for focusing on a particular area [4][5][6][7][8][9][10][11][12][13][14]. For example, in [6,7] longitudinal intensity distribution for a coherent case is considered, [8] considers the process of a plane wave focus using a Fresnel lens, and [9] researches methods of compensation of DOE chromatic aberration.…”

Abstract. The paper presents a feasibility study for an optical system, based on a diffractive membrane. The authors have analyzed structural design of diffractive optical elements for space application and developed finite element models of diffractive lens's carrier and mount. The models were developed for two different schemes: MOIRE project and for the original scheme, developed by the authors. The schemes were analyzed for structural stiffness of the diffractive lens's carrier and mount. The shapes and frequencies of natural oscillations of the carriers of the lens were calculated. The problems of the membrane system's orbit injection and operation were analyzed. An algorithm for the terminal control of the orbital period, eccentricity and longitude of the point of standing of the orbital surveillance system was proposed.Keywords: diffractive optics, space membrane optical system, finite element modeling, space telescope, geostationary orbit Citation: Salmin VV, Karpeev SV, Peresypkin KV, Сhetverikov AS, Tkachenko IS.

Abstract. А possibility of using a diffractive lens as the simplest imaging spectrometer was considered. An experimental construction of the spectral imaging for white, red and green LEDs was conducted. When processing the images the influence of the scattered components of the initial point and nearly points of the image was taken into consideration. There was made a comparison of the received spectral distribution with the spectra of these LEDs, received by means of spectrometer. Root-mean-square error (RMSE) from 8 to 13%.Keywords: diffraction lens, imaging spectrometer, spectral image. Citation: Blank V.A., Skidanov R.V. Diffraction lens in imaging spectrometer.
