Abstract
In this paper, we discussed the method for optimization of fiber-optic surface plasmon resonance (SPR) sensor and the effect of optimized parameters by analysis of the transmission spectrum of waveguide-based SPR sensors. Because of their high sensitivity, the SPR sensors can be used in a lot of chemical and biological studies, but it is difficult to perform a theoretical analysis of an SPR fiber sensor. Therefore, for the design and analysis of the sensor responses, a fiber-optic SPR sensor can be optimized numerically by adjusting parameters such as the thickness of metal layers and the grating period, etc. We simulated and optimized parameters by employing the method of the rigorous coupled wave analysis and the genetic algorithm. Also we discussed the methods for improving sensing capability.
