“…Due to these features, it is possible to control and tune light in PhCs [4], thus opening a new perspective for information processing and technological applications such as chips [5,6], filters [7,8], lasers [9,10], waveguides [11], integrated photonic circuits, sensors [12,13] and thin film photovoltaic cells [14,15], to mention but a few. As is well known, there exist many sort of materials used to form tunable PhCs, such as semiconductors [16], metals [17], superconductors [18,19], metamaterials [20] and liquid crystals [21], among others.…”

We design and evaluate the performance of a one-dimensional photonic crystal (PhC) optical filter that comprises the integration of alternating layers of a barium titanate ferroelectric (BaTiO3) and an yttrium oxide dielectric (Y2O3), with a critical high-temperature superconductor defect, yttrium–barium–copper oxide (YBa2Cu3O7−X), resulting in the (BTO/Y2O3)N/YBCO/(Y2O3/BTO)N multilayered nanostructure array. Here, we demonstrate that such a nanosystem allows for routing and switching optical signals at well-defined wavelengths, either in the visible or the near-infrared spectral regions—the latter as required in optical telecommunication channels. By tailoring the superconductor layer thickness, the multilayer period number N, the temperature and the direction of incident light, we provide a computational test-bed for the implementation of a PhC-optical filter that works for both wavelength-division multiplexing in the 300–800 nm region and for high-Q filtering in the 1300–1800 nm range. In particular, we show that the filter’s quality factor of resonances Q increases with the number of multilayers—it shows an exponential scaling with N (e.g., in the telecom C-band, Q≈470 for N=8). In the telecom region, the light transmission slightly shifts towards longer wavelengths with increasing temperature; this occurs at an average rate of 0.25 nm/K in the range from 20 to 80 K, for N=5 at normal incidence. This rate can be enhanced, and the filter can thus be used for temperature sensing in the NIR range. Moreover, the filter works at cryogenic temperature environments (e.g., in outer space conditions) and can be integrated into either photonic and optoelectronic circuits or in devices for the transmission of information.

“…Due to the fast technological advances in optoelectronics, optics, and telecommunications, studies on optical structures have gained momentum (Barrientos-Garcia et al, 2016;Li et al, 2016;Han et al, 2021;Kaburcuk and Elsherbeni, 2021). There are many studies in the literature on optical structures, such as metamaterials and photonic crystals (Sung et al, 2011;Alipour-Banaei et al, 2017;Chen et al, 2017;Zhang et al, 2018;Benhaddad et al, 2019;Napolskii et al, 2020;Shi et al, 2020;Singer et al, 2020). Phononic structures affected by sound waves also show structurally similar properties to photonic crystals among optical structures (Lu et al, 2017;Sun et al, 2019;Ayman et al, 2020;Rostami et al, 2020;Trzaskowska et al, 2020;Rostami et al, 2021).…”

In this study, electromagnetic wave propagation frequencies are investigated in four different photonic crystal structures, three of which are tripartite and one of which is bipartite. In addition, the effects of part lengths and material property parameters (ε, µ) of these structures on electromagnetic wave frequencies are examined. The photonic crystal structures are one-dimensional (1D) and the parts of these structures have different lengths. Differences in the part lengths allow the electromagnetic wave frequencies to be adjusted. The material property parameters of each part of the photonic crystal structures change in the x-axis direction and the default values of these parameters theoretically change from 1 to 2. The values for the first three modes of electromagnetic wave frequencies obtained for four different photonic crystal structures are different from each other. The lowest values of the electromagnetic wave frequencies are obtained for the first photonic crystal structure (S1) with the shortest first and second part lengths.

“…polarization rotators [33] and light-harvesting [13]. Furthermore, PCs are gaining much interest in optical integrated networks and communication systems [34,35], slow light devices [36] and optical power splitters [37]. Most of these applications are essentially based on the tunability of the PBGs using some internal and external effects to change the permittivity of the constituent materials.…”

Sensitivity enhancement of annular one dimensional photonic crystals temperature sensors with nematic liquid crystals

2020

View full text Add to dashboard Cite

A novel design of one dimensional annular photonic crystals with a low birefringence nematic liquid crystal as a defect layer is introduced. The output field of the sensor structure is plotted after different optimization steps on all constituents such as thickness and core radius of the starting medium. The performance of the sensor was studied using different quality parameters such as sensitivity, figure of merit, detection limit and resolution. The designed sensor exhibits a sensitivity of about 0.224 nm °C−1 due to the presence of the liquid crystal material. The proposed sensor design can be used as a narrowband optical filter in the visible region around two wavelengths: 600 nm and 700 nm. As an optoelectronic device, this structure can serve as a temperature sensor with higher sensitivity than the conventional one dimensional photonic crystal structures and photonic crystals fibers.
