“…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.

“…Q is defined as the ratio of frequency of the defect mode peak to the FWHM of the transmission peak. Mathematically, [40]. We investigate the quality factor of the filter with respect to different applied magnetic field, incident angles, plasma layer thickness, and plasma density, which is depicted in figure 9.…”

The present research demonstrates the tunable filtering properties of a single/multi-channel filter based on 1D photonic crystal (PhC), which is designed with dielectric materials (A, B) and magnetized cold plasma (P). The proposed filter has a configuration of A/BMA/P/BN(A/B)MTransmission spectra of the structure is investigated for both right-hand polarization and left-hand polarization configurations of the plasma material by employing the well-known transfer matrix method. It is found that number of period of the plasma layer (N) decides the single-channel and multi-channel operation of the filter. It is revealed that the external magnetic field can be manipulated to tune the frequency of the filter. Also, it is found that the geometrical parameters such as thickness of the plasma layer, plasma density, and incident angle play a significant role in tuning the defect mode frequency. Moreover, the color map plot is studied to provide a clear insight of shifting nature of the defect mode frequency. Quality factor of the filter is evaluated vis-à-vis different geometrical parameters. Our considered structure can be the mainstay for filtering applications in microwave regions, and can find suitable applications in dense wavelength division multiplexing and high speed signal processing.
