“…Ultrafast ferroelectric polarization switching is also known in BTO thin films. , In a recent study, in a BTO-embedded optical microcavity, the steady-state nonlinear absorption at 532 nm showed cavity-dependent enhancement. , In general, the BTO alone has been proven to be a potential nonlinear and ferroelectric switching material, whereas the photonic structure-influenced BTO hot carrier ultrafast dynamics of electron–photon interaction is interesting and has not been explored so far. Recent reports on photonic and phononic responses of 1D photonic crystals envisaged a strong path toward nonlinear optic, refractive sensing, biological sensing, gas sensing, and optical filtering applications. − …”

The ultrafast absorption dynamics of photonic modes and enhanced features of electronic states have been demonstrated in a barium titanate (BaTiO 3 , BTO)-embedded onedimensional photonic crystal. The photonic structure has been realized as an optical microcavity, where a BTO central layer is sandwiched between two SiO 2 /TiO 2 -distributed Bragg reflectors. Angle-dependent transient absorption behavior reveals the excitedstate absorption dynamics of cavity-tuned BTO defect energies. Furthermore, the dynamic evolution of photonic minibands of both sides of the photonic cavity mode demonstrates the enormous cavity field confinement effect. The temporal evolution of nonlinear absorption dynamics is specific to cavity angle tuning and is evidenced by seven orders of two-photon absorption enhancement in BTO mid-bandgap energies. Overall, the results highlight the impact of strong optical field confinement within the BTO central layer. The simulations of spatial and angledependent localized optical field and energy deposition within the photonic structure further support the experimental findings. The enhanced features of ultrafast absorption dynamics and strong optical nonlinearities of the BTO-based active photonic structure offer a better understanding of electron−photon interaction, which paves the way for many novel nonlinear, hybrid optoelectronic, and photonic device applications.

“…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. In this work, we focus on a critical high-temperature superconductor material, YBa 2 Cu 3 O 7−x , as a defect layer inside the photonic crystal.…”

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.

“…Temperature dependences of the transmission spectra of hybrid multifunctional superconducting YBa2Cu3O7 photonic crystals were studied in Ref. [14]. Using the influence of the thermo-optical and thermal expansion effects in the polymer, a temperature sensor was designed on the base of a ternary PC [15], which operates by measuring the red shift of the transmission peak with an increase of the temperature.…”

We study the influence of thermal expansion and thermo-optic effect on optical properties of finite one-dimensional three-periodic photonic crystals of structure [(ab) N (cd) М ] K composed of four different nonmagnetic dielectric materials a, b, c, and d. We calculate temperature dependencies and incidence angle dependencies of the transmittivity of TE-and TM-polarized electromagnetic waves, as well as the distribution of energy within these structures. The optimal adjustment of photonic crystal bandgap centers for obtaining the desired transmission characteristics of the temperature-governed photonic bandgap structures is found, and the peculiarities of the energy distributions inside the photonic system are investigated. We propose a sensitive thermal polarization TE|TM switch as well as angular and temperature sensors working at the intraband-mode frequencies exploiting temperature effects.
