Special Issue Information

Dear Colleagues,

The combination of optical technology progress and novel analytical methodologies allows promising applications to be developed and optimized in the fields of clinical diagnosis, optical sensing, nanomaterial-based technologies, bioanalysis, integrated optics, and renewable energies. Holographic interferometry and holographic lithography are useful optical techniques to develop elements for such applications.

Today, advanced materials are of great interest to bring these optical and photonic elements into our daily lives. Photopolymers, photoresists, hydrogels, and those based on nanoparticles, transition metals, ionic liquid crystals, chalcogenides, or azobenzenes are some of the most used materials in holography. Their design, functionalization, and manufacture are key factors in obtaining specific properties for real applications.

The aim of this Special Issue is to collect both original research articles and review papers on the most recent developments regarding the modeling, fabrication, design, or characterization of different optical systems, with special emphasis on holographic elements and materials for obtaining sensors and biosensors, solar concentrators, and novel waveguides. Papers related to clinical assays or diagnosis of the COVID-19 virus are welcome. Reviews describing the possible role of holography in such virus are also invited for publication.

Most 3D augmented reality, near-eye displays suffer from a low field of view. Leaky-mode lithium niobate devices are often used to steer, multiplex, or otherwise control the path of light in a system. Such devices are ideal candidates for creating such displays, and, in this paper, we demonstrate a path to increasing their view angle to 180° by curving the substrate, which will steer the output light toward the user’s eye. We also model the tradeoff between field of view, allowable interaction length, and draw distance for these curved leaky-mode devices. Full article

Title: Fabrication of High Efficiency Volume Phase Holograms in Silver Halide Materials for Solar Concentrator Application

Authors: H.R. Pratheep, V. Vadivelan, and B. Chandar Shekar

Abstract: The commercial PV cells are made up with silicon but at the same time crystalline silicon has some drawbacks of too costly, installation price is too high, need large area for installation, conversion output efficiency is very low and need a separate tracking system. Using the alternative technology of Conventional Solar Concentrators (CSC) like mirrors, lenses can overcome those issues but at the same time it will create more heat on PV cells. The nature of PV cells utilizing only visible wavelengths for electricity conversion and all other wavelengths are strongly affecting the solar cell’s self- life. These problems can be solved by using Holographic Solar Concentrators (HSC) in the solar panel. In this paper we fabricate and discuss about the Volume Phase Holograms (VPH) for solar concentrator applications. In this work the He-Ni (632.8 nm 25 mW) laser was used to record the VPH in Silver Halide (SH) materials having 76.9% output efficiency reported here. We used Silver SH holographic emulsion for the fabrication and this emulsion has 20000 lines/mm spatial resolutions with 8 nm grain size. The exposure energy of 150 µJ/cm2 is given and the calculated time is 700 ms with the laser power is about 430 µW at the recoding plane. At the end we measured the HSC by three different lasers of 442 nm He-Cd,  532 nm Diode Pumped Solid State (DPSS) laser and 632.8 nm Hi-Ne with different angles. This VPH can be used to collect visible wavelength from sunlight into PV cells to boost up the output efficiency.
