“…However, the increase in sensitivity is not significant. This is explained by the fact that there is a trade-off between sensitivity and FOM in the GMR-based sensors [31,32] . It can be seen from Fig.…”

A high performance optical sensor based on a double compound symmetric gratings (DCSGs) structure is designed. The reflection spectrum of the DCSG is investigated by utilizing a method that combines a theoretical model with the eigenmode information of the grating structure. The theoretical results, which are observed to agree well with those acquired by rigorous coupled-wave analysis, show that the linewidth of the reflection spectrum decreases upon the increasing distance between the grating strips. This research work will lay a foundation for studying high performance integrated optical sensors in miniature nanostructures.

“…Depending on the various configurations covered in the literature concerning the metal-dielectric interfaces, the hybrid resonant elements can be classified under the following categories: i) dielectric grating on metal surface, [52,197,198] ii) dielectric grating + waveguide on metal surface, [199,200] iii) metallic grating (broader width) + dielectric waveguide, [201] iv) metal coated dielectric grating + waveguide, [202] v) metal coated dielectric grating, [203] vi) metal coated dielectric grating + metal coated dielectric waveguide. [204] Because of the metallic coating, the structures are optically characterized primarily under the reflection scheme for wavelength/angular-based interrogations. Irrespective of the configurations, the metal-dielectric interface generates SPP waves under TM polarized excitation, matched by the grating vector.…”

The requirements for an optical sensor are high: the sensor should be reliable, quick, and simple, and all these features must be provided at ultralow fabrication costs. The requirements go even further, as the sensor may operate without an energy source, and nowadays, the sensor components should be recyclable. Today existing plasmonic concepts and advances in nanofabrication can meet these requirements. This review article describes the available nanoscale components and discusses their reasonable layout to obtain the sensing requirements. It is shown that combining photonic and plasmonic properties helps to get high sensitivity at low losses, where these hybrid modes with simple optical concepts are introduced. The current state of the art in developing lithographic nanostructuring and directed self‐assembly to pave the way for future refractive index sensors is also used. By providing a guideline for advanced sensors, how the individual optical components can be used to create hybrid properties that can be realized cost‐effectively are shown. The review article ends with a discussion on the perspectivs for plasmonic hybridization sensors.

“…The sensitivity of such a structure is 338.5 nm/RIU, increased by a factor of 1.5 over conventional structures [17]. Wang et al proposed a hybrid guided-mode resonance/surface plasmon resonance structure to increase sensitivity to 1087 nm/RIU with a resonance wavelength of 1796.1 nm [25]. These reports demonstrated obvious sensitivity enhancement.…”

Guided-mode resonance (GMR) sensors are widely used as biosensors with the advantages of simple structure, easy detection schemes, high efficiency, and narrow linewidth. However, their applications are limited by their relatively low sensitivity (<200 nm/RIU) and in turn low figure of merit (FOM, <100 1/RIU). Many efforts have been made to enhance the sensitivity or FOM, separately. To enhance the sensitivity and FOM simultaneously for more sensitive sensing, we proposed a metal layer-assisted double-grating (MADG) structure with the evanescent field extending to the sensing region enabled by the metal reflector layer underneath the double-grating. The influence of structural parameters was systematically investigated. Bulk sensitivity of 550.0 nm/RIU and FOM of 1571.4 1/RIU were obtained after numerical optimization. Compared with a single-grating structure, the surface sensitivity of the double-grating structure for protein adsorption increases by a factor of 2.4 times. The as-proposed MADG has a great potential to be a biosensor with high sensitivity and high accuracy.
