Design of one dimensional defect based photonic crystal by composited superconducting material for bio sensing applications

A novel biosensor based on 1-D defect photonic crystal is suggested to be consisting of alternate layers of SiO2 and Air. At the middle, there exists a cavity layer encapsulated with a composite layer of superconducting and dielectric materials. The blood samples are infiltrated in the cavity. The s...

Summary:A novel biosensor based on 1-D defect photonic crystal is suggested to be consisting of alternate layers of SiO2 and Air. At the middle, there exists a cavity layer encapsulated with a composite layer of superconducting and dielectric materials. The blood samples are infiltrated in the cavity. The sensitivity is calculated at different parameters including filling factor of superconducting materials, the temperature, and the width of the cavity. Results indicate that the sensitivity decrease slightly as temperature increases and sensitivity increases as filling factor increases and thickness of cavity increases.
