Design and Analysis of Optical Sensor for Detection of Cancer Biomarkers

The proposed paper incorporates the modeling and simulation of the highly sensitive photonic crystal-based sensor for breast and cervical cancer infected cell detection. Two structures, regular hexagon, and 180° phase mismatched hexagon are used. For the detection of cancer infected cells, the change in refractive index is considered as the basis and corresponding change in properties of light rays is observed. A comparative study has been done for the sensitivity of the designed sensor. The results are observed with the wavelength shift in the transmitted spectrum. The sensitivity is calculated for both the structures and found that 180° phase mismatch is better than hexagonal shape as regards to cervical cancer detection, hexagonal structure fares better than 180⁰ phase mismatch for breast cancer detection with regards to performance in sensitivity.
