Abstract: (1628 Views)
Nowadays, many researches have been conducted on utilizing optical biosensors but main challenges regarding this type of biosensor are sensitivity and detection limit. In this research design and simulation of optical biosensor based on micro Bezier ring resonator were studied, which includes a ring resonator with a bus waveguide. Finally, the optimum quality factor has been obtained via Taguchi algorithm, in which optimum values of geometrical parameters are calculated while the ring radius is fixed. The best optimized structure is acquired to be Bezier ring resonator with a Bezier number of 0.4, a gap of 250 nm, height of 250 nm and width of 480 nm, which yields a quality factor of 66236, and an FSR of 28.8 nm. This structure has 4.43 times more quality factor in comparison with the other type of Bezier ring resonator.
