High-performance intensity-interrogated magneto-optic surface plasmon resonance (MOSPR) sensors are designed by a multi-objective optimization approach. Designed devices show bulk refractive index sensitivity 1 order of magnitude larger than the current state of the art, while the design procedure allows to chose an appropriate trade-off between sensor performance and ease of fabrication. Straightforward guidelines for the sensor design and fabrication emerge from the optimization process, indicating that minimization of the optical losses takes precedence on the maximization of the magneto-optical modulation.

Abstract
High-performance intensity-interrogated magneto-optic surface plasmon resonance (MOSPR) sensors are designed by a multi-objective optimization approach. Designed devices show bulk refractive index sensitivity 1 order of magnitude larger than the current state of the art, while the design procedure allows to chose an appropriate trade-off between sensor performance and ease of fabrication. Straightforward guidelines for the sensor design and fabrication emerge from the optimization process, indicating that minimization of the optical losses takes precedence on the maximization of the magneto-optical modulation.
