We theoretically analyze the sensing properties of a one-dimensional photonic crystal-based biosensor for detecting cancer cells infiltrated in a defect cavity layer. The biosensor consists of a sample cavity layer sandwiched between two identical photonic crystals of Hgba2Ca2Cu3O8+ and GaAs. We use the transfer matrix method to evaluate the performance of the biosensor. We show that a defect mode appears in the transmission spectrum of the biosensor that its position depends on the type of cancer cells in the cavity layer. The analysis is carried out by comparing the transmittance peaks of the cancer cells with the normal cells. We investigate the performance of the biosensor under different hydrostatic pressures and temperatures. We show that one can use temperature change to fine-tune the frequency of the defect modes. In addition, we can adjust the working area of the biosensor by changing the hydrostatic pressure. It is shown that the sensitivity of the biosensor is independent of the temperature, while it strongly depends on the hydrostatic pressure.

In this paper, the properties of wide-angle and ultra-wideband (UWB) absorption of onedimensional (1-D) superconductor photonic crystals (SPCs) in the terahertz (THz) region are theoretically analyzed by transfer matrix method (TMM). We principally study the absorption features in SPCs with different arrangements by contrast where their external factors and dielectric types are consistent. The arrangements of SPCs adopt two construction rules of generous Fibonacci sequence (GFS) and Cantor-like sequence (CLS). In addition, the influences of the recursive numbers, external factors and polarizationdepend properties on the proposed structures are also considered. We introduce multifractal theory to describe the absorption trends and self-similarity of quasi-periodic structural system subtly specific to the variation of recursive numbers. Moreover, the reason for angle-insensitive absorption is also investigated via the interference field theory. The calculated results demonstrate that the UWB absorption can sustain over 80 degrees within THz region for transverse magnetic (TM) wave at high temperature in the proposed SPCs, which provides theoretical guidance for the design of the high-performance THz absorber.

“…15 For this reason, the defect modes have been used for filters only under the limit of the normal incidence being at a particular wavelength; otherwise, transmission peaks appear at the other wavelengths under oblique incidence. [16][17][18] Recently, compared with traditional all-dielectric Fabry-Pérot interference filters, 19,20 various designs have been proposed for novel features, such as graphene, 21 superconductor, [22][23][24] semiconductor, 25 and liquid crystal 26 -dielectric PCs. To overcome the angular effect influences, some innovative reports have been published, in which negative refractive-index materials, 27 hyperbolic metamaterials, 28,29 and so on were selected as special performance materials to achieve insensitivity to incident angle and polarization.…”

Angular-adjustable single-channel narrow-band filter based on one-dimensional photonic crystal heterostructure

et al. 2021

In this work, we designed a narrow-band filter based on a one-dimensional photonic crystal heterostructure featuring an angle-adjustable single-channel. The design presented here is based on a quarter-wave reflector with a mirror defect layer in the middle of the structure. By combining two defective one-dimensional photonic crystals (PCs), we obtained a heterostructure in which the two sub-PCs had the wavelengths of their defect modes, that is, the same at one incident angle and different at all other incident angles. This structure possessed the single-channel resonant peak in the transmission spectrum under either a normal or an oblique incident angle, and the angle-adjustability was related to the two modifying parameters. The filter based on this heterostructure possessed not only a narrow passband but also a sharp angular pass breadth. These properties have potential applications in angular tunable, single-channel narrow-band filters.
