ABSTRACT

In recent decades, extensive studies have been conducted on biosensors. Of these, biosensors are of great importance, and various photonic structures have been used to design these types of sensors. In this work, optimization of the performance of photonic crystal-based biosensor has been addressed. The nano-resonant sensor is within the structure and is surrounded by two waveguides. The resonator is formed by the smaller air cavities. In order to increase the optical constraint and better coupling of light between the waveguides and the resonator, two finis waveguides have been used. By connecting the biological molecule to the measuring cavity wall, its refractive index will change and the wavelength of the resonant structure will be shifted. Several parameters such as number, thickness of layers and slope affect this sensitivity. By optimizing these parameters, changes in the refractive index can be detected.
