We studied the optical fractal effect of the one-dimensional distributed feedback Bragg photonic crystals formed by semiconductor GaAs and dielectric TiO2. Light wave is transmitted in the intermediate dielectric slab and reflected back by the periodic photonic crystals at both ends, forming multiple fractal resonance output. The transmission channels expand exponentially by thickening the bulk in a cryogenic environment. The quality factor of each fractal resonant state improves with a greater periodic number of crystals. Furthermore, central wave of resonance has a blue-shift as the external pressure increases, while the influence of environment temperature on the fractal resonance could be ignored. It is hoped that our study can highlight the potential of these findings for designing multi-channel communication filters in cryogenic environments.

“…Segundo, la función dieléctrica de un superconductor (la cual define el comportamiento óptico del material) depende principalmente de la temperatura y el campo magnético externo(González et al, 2020). Debido a esto, los materiales superconductores de alta temperatura resultan interesantes para la implementación de cristales fotónicos sintonizables en una amplia variedad de aplicaciones tales como sensores de temperatura, filtros policromáticos y biosensores, entre otros(Chen et al, 2022;Hao et al, 2020;Soltani et al, 2021;Zaky & Aly, 2020).En este artículo(González et al, 2022), se caracteriza y diseña computacionalmente un filtro óptico unidimensional que puede ser integrado en redes ópticas basadas en multiplexación por longitud de onda (WDM, por sus siglas en inglés), con un alto factor de calidad Q, que transmite información en el rango visible e IR cercano en ambientes de muy baja temperatura como las del espacio exterior.…”

“…Superconductor materials used for PhC fabrication present the following advantages: (i) the damping emission (losses) of electromagnetic waves that occur in metals are improved with the use of superconductors, and (ii) the superconductor dielectric function depends on the London penetration depth, which is a function of temperature and the external magnetic field. Due to this, high-temperature superconductor materials convey an interesting opportunity for the implementation of tunable photonic crystals in a wide variety of applications such as temperature sensors [17,22], polychromatic filters [23] and biosensors [24], among others.…”

A Multichannel Superconductor-Based Photonic Crystal Optical Filter Tunable in the Visible and Telecom Windows at Cryogenic Temperature

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.
