Theoretical Study of Symmetrical 1D Photonic Crystal as a Blood Cancer Sensor

In this work, we studied by simulation the performance of a cancer sensor based on 1D symmetrical photonic crystal. The proposal 1D photonic crystal structure is (AB)⁵C(BA)⁵ where A = TiO₂ with high refractive index, B = SiO₂ with low refractive index and layer C is a blood cell. The study was conducted using the Transfer Matrix method (TMM) method. So, the transmissions spectra, the sensitivity as well as the quality factor of the sensor for different blood cell samples including normal blood cells and various cancerous blood cells: Jurkat, HeLa, PC-12, MDA-MB-231, and MCF-7 were obtained. The obtained results have shown the improvement in the performance of the proposal 1D photonic crystal sensors, namely sensitivity and quality factor, as a function of the thickness of the sample layer C and the angle of incidence in case of the two polarization mode.
