Design of 2D photonic crystal biosensor to detect blood components

Abstract

Photonic crystals are periodic structures made of insulators. They are the best option to design biosensors. In this paper, a photonic crystal biosensor containing insulation rods in the air was designed and simulated. This biosensor was used as a photonic crystal circular nano-ring between the internal and external waveguides. At the end of the internal waveguide, a defect exists to create an increase in the coupling distance. This causes the quality factor and resonant wavelength displacement to increase. The purpose of designing this sensor is to check blood ingredients. After connecting to a measuring rod, this sensor shows different refractive indices. Another important characteristic of the proposed structure is that mostly radiuses of dielectric rods are identical. This causes the sensor construction to be easy. The plane-wave expansion (PWE) method is utilized to calculate the band structure. The results show that a photonic band gap (PBG) with a wavelength from 1.26 μm to 1.92 μm is created in this distance where no wavelength can spread.

Sensing and Detection Capabilities of One-Dimensional Defective Photonic Crystal Suitable for Malaria Infection Diagnosis from Preliminary to Advanced Stage: Theoretical Study

“…Recently, Zina et al suggested how 1D PC consisting of cold magnetic plasma and quartz materials according to the Copper mean sequence can be used for the detection of the magnetic field direction by studying the external magnetic field dependent movement of ultra large PBG of the structure [39]. Parandin et al suggested a 2D photonic biosensor made up of circular nano-rings between the waveguides for the detection of various blood components [40,41]. Liu et al demonstrated how a 2D PC based cavity structure can be used as a quality sensor for the detection of ethanol [42].…”
