“…This combination produces a multi-resonance behavior related with low-order diffraction orders. This hybridization has been already presented in recent contributions [30], [31], but the ultra-narrow hybridized resonances reported in this paper generate higher sensitivity and FOM, that expands over a wide dynamic range with reasonable performance. The device operates under normal incidence conditions, easing its integration for both illumination and signal retrieval systems, and allowing to locate it at the tip of an optical fiber.…”

We configure and analyze a nanostructured device that hybridizes grating modes and surface plasmon resonances. The model uses an effective index of refraction that considers the volume fraction of the involved materials, and the propagation depth of the plasmon through the structure. Our geometry is an extruded low-order diffraction grating made of dielectric nano-triangles. Surface plasmon resonances are excited at a metal/dielectric interface, which is separated from the analyte by a high-index dielectric layer. The optical performance of the refractometric sensor is highly competitive in sensitivity and figure of merit (FOM) because of the the ultra-narrow spectral response (below 0.1 nm). Moreover, it is operative within a wide range of the index of refraction (from 1.3 till 1.56), and also works under normal incidence conditions.

“…Primarily, a resonant mode associated with a dielectric grating emerges at the highest-energies (~500 nm) while several plasmonic modes are excited at lower energies due to the change in sign of the real permittivity across the WS 2 /Au interface ( Fig. 3e) 23,24 . Characteristic mode profiles are shown in Fig.…”

Van der Waals materials and heterostructures that manifest strongly bound exciton states at room temperature also exhibit emergent physical phenomena and are of great promise for optoelectronic applications. Here, we demonstrate that nanostructured, multilayer transition metal dichalcogenides (TMDCs) by themselves provide an ideal platform for excitation and control of excitonic modes, paving the way to exciton-photonics. Hence, we show that by patterning the TMDCs into nanoresonators, strong dispersion and avoided crossing of exciton, cavity photons and plasmon polaritons with effective separation energy exceeding 410 meV can be controlled with great precision. We further observe that inherently strong TMDC exciton absorption resonances may be completely suppressed due to excitation of hybrid light-matter states and their interference. Our work paves the way to the next generation of integrated exciton optoelectronic nano-devices and applications in light generation, computing, and sensing.

“…In grating-coupled SPR configurations, the grating is inscribed in the metallic coating and is used as a coupler to adjust the propagation constant of light incident to the metal [ 91 ]. As an alternative to the metal grating, periodic corrugations could be fabricated on the fiber surface or fiber tip, where metal is deposited over the dielectric grating [ 92 ].…”

Surface Plasmon Resonance (SPR) fiber sensor research has grown since the first demonstration over 20 year ago into a rich and diverse field with a wide range of optical fiber architectures, plasmonic coatings, and excitation and interrogation methods. Yet, the large diversity of SPR fiber sensor designs has made it difficult to understand the advantages of each approach. Here, we review SPR fiber sensor architectures, covering the latest developments from optical fiber geometries to plasmonic coatings. By developing a systematic approach to fiber-based SPR designs, we identify and discuss future research opportunities based on a performance comparison of the different approaches for sensing applications.
