“…Highly absorbent photonic structures have recently received much attention due to their potential applications in solar cells [ 20 , 21 , 22 ], electro-optic detectors [ 23 , 24 ], and heat emitters [ 25 , 26 , 27 , 28 ]. In particular, Gires–Tournois (GT) resonators composed of thin films on a reflective metal mirror have been successfully demonstrated to promote ultrahigh absorption and strong light–matter interactions with multibeam interference and a slow-light effect [ 29 , 30 , 31 , 32 , 33 , 34 , 35 ]. This geometry exhibits numerous advantages, such as simple fabrication, facile spectral tuning, omnidirectional strong absorption, and the possibility of active modulation of absorption.…”

“…Based on these promising properties, considerable studies have been conducted to explain optical properties, such as the conditions for the ultrahigh absorption of these systems using impedance or admittance matching analysis or assuming a constant tangential electric or magnetic field [ 33 , 34 , 36 ]. Recently, GT resonators using nonlinear effective phase change have been widely studied as planar metasurfaces, including dynamic phase change absorbers, achromatic surface clocking and lenses, and colored perovskite solar cells [ 32 , 33 , 34 , 35 , 37 ]. Nevertheless, these powerful resonators, capable of various media combinations, have still not been optimized in unique conditions for strong absorption with sensitive slow-light for biosensing applications, such as low refractive index (RI) virus detection.…”

Over the past few decades, advances in various nanophotonic structures to enhance light–matter interactions have opened numerous opportunities for biosensing applications. Beyond the successful development of label-free nanophotonic biosensors that utilize plasmon resonances in metals and Mie resonances in dielectrics, simpler structures are required to achieve improved sensor performance and multifunctionality, while enabling cost-effective fabrication. Here, we present a simple and effectual approach to colorimetric biosensing utilizing a trilayered Gires–Tournois (GT) resonator, which provides a sensitive slow-light effect in response to low refractive index (RI) substances and thus enables to distinguish low RI bioparticles from the background with spatially distinct color differences. For low RI sensitivity, by impedance matching based on the transmission line model, trilayer configuration enables the derivation of optimal designs to achieve the unity absorption condition in a low RI medium, which is difficult to obtain with the conventional GT configuration. Compared to conventional bilayered GT resonators, the trilayered GT resonator shows significant sensing performance with linear sensitivity in various situations with low RI substances. For extended applications, several proposed designs of trilayered GT resonators are presented in various material combinations by impedance matching using equivalent transmission line models. Further, comparing the color change of different substrates with low RI NPs using finite-difference time-domain (FDTD) simulations, the proposed GT structure shows surpassing colorimetric detection.

prompted a renewed interest in asymmetric Fabry-Pérot (FP) cavities, also termed Gires-Tournois resonators. They are comprised of one optically thick and one optically thin metallic mirror through which light can enter the structure. These optical elements are known for their ease of fabrication and effectiveness in resonating and enhancing light-matter interaction at selected wavelengths. [4,6,7] The general strategy to achieve dynamic tuning in FP resonators is to replace the passive insulator that commonly sits between the mirrors by dynamically tunable materials such as graphene, [11][12][13] phase-change magnesium, [14] electro-optical polymers, [15] liquid crystals (LCs) [16][17][18] and conducting oxides [19][20][21] via the field-effect. [22] Several works showed that electrical gating of indium-tin-oxide incorporated in the cavity facilitates control over light absorption [12,19] and its reflection phase in mid-infrared [20] and near-infrared. [21] Other research exploited electrochromic oxide [23] and polymers [24][25][26] with nanostructures to tune the resulting reflected color. Researchers showed that optical pumping of gallium-doped zinc oxide [27] and alumina [28] allows for ultrafast modulation of cavity resonances in a sub-picosecond regime. Tuning can also be achieved in non-conventional ways by light pressure, [29] directed self-assembly of nanoparticles in a liquid electrolyte [30] and by phase-tunable meta-mirrors. [31] To reduce fabrication complexity, a large variety of responsive materials Tunable metal-insulator-metal (MIM) Fabry-Pérot (FP) cavities that can dynamically control light enable novel sensing, imaging and display applications. However, the realization of dynamic cavities incorporating stimuliresponsive materials poses a significant engineering challenge. Current approaches rely on refractive index modulation and suffer from low dynamic tunability, high losses, and limited spectral ranges, and require liquid and hazardous materials for operation. To overcome these challenges, a new tuning mechanism employing reversible mechanical adaptations of a polymer network is proposed, and dynamic tuning of optical resonances is demonstrated. Solid-state temperature-responsive optical coatings are developed by preparing a monodomain nematic liquid crystalline network (LCN) and are incorporated between metallic mirrors to form active optical microcavities. LCN microcavities offer large, reversible and highly linear spectral tuning of FP resonances reaching wavelength-shifts up to 40 nm via thermomechanical actuation while featuring outstanding repeatability and precision over more than 100 heating-cooling cycles. This degree of tunability allows for reversible switching between the reflective and the absorbing states of the device over the entire visible and near-infrared spectral regions, reaching large changes in reflectance with modulation efficiency ΔR = 79%.

“…However, the difficulties in nanostructure fabrication, such as large-area manufacturing, size control at nanoscale, and cost, seriously hinder their practical applications. In contrast, the planar multilayer structures based on surface-state resonances are the most promising candidates to achieve desired selective emission over a large area, which can mitigate the fabrication limitations of nanostructures [ 32 , 33 , 34 , 35 , 36 , 37 ].…”

Thermal emitters with properties of wavelength-selective and narrowband have been highly sought after for a variety of potential applications due to their high energy efficiency in the mid-infrared spectral range. In this study, we theoretically and experimentally demonstrate the tunable narrowband thermal emitter based on fully planar Si-W-SiN/SiNO multilayer, which is realized by the excitation of Tamm plasmon polaritons between a W layer and a SiN/SiNO-distributed Bragg reflector. In conjunction with electromagnetic simulations by the FDTD method, the optimum structure design of the emitter is implemented by 2.5 periods of DBR structure, and the corresponding emitter exhibits the nearly perfect narrowband absorption performance at the resonance wavelength and suppressed absorption performance in long wave range. Additionally, the narrowband absorption peak is insensitive to polarization mode and has a considerable angular tolerance of incident light. Furthermore, the actual high-quality Si-W-SiN/SiNO emitters are fabricated through lithography-free methods including magnetron sputtering and PECVD technology. The experimental absorption spectra of optimized emitters are found to be in good agreement with the simulated absorption spectra, showing the tunable narrowband absorption with all peak values of over 95%. Remarkably, the fabricated Si-W-SiN/SiNO emitter presents excellent high-temperature stability for several heating/cooling cycles confirmed up to 1200 K in Ar ambient. This easy-to-fabricate and tunable narrowband refractory emitter paves the way for practical designs in various photonic and thermal applications, such as thermophotovoltaic and IR radiative heaters.
