Sensitivity Analysis of 2D Photonic Crystal based Hexoganal Ring Resonator for Cervical Cancer Detection

Abstract

In this effort, we propose a two dimensional hexagonal ring resonator sensor (2DHRR) for the detection of cervical cancer cell in the women's cervix. Hexagonal ring structure is widely used among research community. This device is based on silicon rods surrounded by air. The detection process is to be done by means of refractive index involved in simulation which creates different position in transmission peaks. It creates a shift which is used to calculate sensitivity. Two sensor design structures are created, analyzed and compared by having analyte in it. The OptiFDTD algorithm plays a role to simulate the transmission of light. The 2DHRR sensor has the sensitivity of 790nm/RIU and the quality factor as 344. The second one which is Inverse 2DHRR sensor has its sensitivity as 570nm/RIU and the quality factor to be 310. The high sensitivity is noticed in 2DHRR sensor. It also retains the high quality factor. The effects of results are promising by means of providing compact size, low power consumption and less weight. Also, this research has got comparatively high sensitivity with which we can even go for with fabrication process.
