Superconductor–semiconductor one-dimensional photonic crystal using a cancer cell as a defect layer

Abstract

In this work, we calculate the transmittance spectrum for a one-dimensional photonic crystal composed by alternating superconductor and semiconductor layers. For these purposes, we shall consider the critical temperature of the superconductor that depends on the hydrostatic pressure, while the dielectric constant and layer thickness of the semiconductor depends on pressure. First, we insert a cavity with zero-cancer, Jurkat, and MCF-7 cells into the crystal. Then, using the transfer matrix method and the two-fluid model, we observed a defect mode within the photonic gap. The predominating response from the defect mode is mostly because of the hydrostatic pressure applied to the structure since confinement within the cavity is greater for zero-cancer cells, as determined by the quality factor. Herein, we may also observe that the defect mode shifts towards shorter frequencies as the layer thickness of the cavity increases for the crystal.
