Circular dichroism based refractive index sensing using chiral metamaterials.
A new strategy to improve the sensing ability of localized surface plasmon resonance sensors is presented. By employing chiral plasmonic nanostructures, circularly polarized differential transmittance can show enhanced sensing performance over circularly polarized transmittance under certain conditions.
متن کاملUltrasensitive Magnetic Field Sensing Based on Refractive-Index-Matched Coupling
An ultrasensitive magnetic field sensor is proposed and investigated experimentally. The no-core fiber is fusion-spliced between two pieces of single-mode fibers and then immersed in magnetic fluid with an appropriate value of refractive index. Under the refractive-index-matched coupling condition, the guided mode becomes leaky and a coupling wavelength dip in the transmission spectrum of the s...
متن کاملRefractive Index Sensor Based on a Metal–Insulator–Metal Waveguide Coupled with a Symmetric Structure
In this study, a new refractive index sensor based on a metal-insulator-metal waveguide coupled with a notched ring resonator and stub is designed. The finite element method is used to study the propagation characteristics of the sensor. According to the calculation results, the transmission spectrum exhibits a typical Fano resonance shape. The phenomenon of Fano resonance is caused by the coup...
متن کاملA Refractive Index Sensor Based on a Metal-Insulator-Metal Waveguide-Coupled Ring Resonator
A refractive index sensor composed of two straight metal-insulator-metal waveguides and a ring resonator is presented. One end of each straight waveguide is sealed and the other end acts as port. The transmission spectrum and magnetic field distribution of this sensor structure are simulated using finite-difference time-domain method (FDTD). The results show that an asymmetric line shape is obs...
