“…Figure d,e is the measured spectra of fresh and postthermal‐treated device after bonding. The accumulated thermal effect in the bonding process leads the undesired residual stress to the structure and changes material property to some extent, so the spectral shift and shrink are observed other than severe distorion at 6.5–7 µm (in the Supporting Information). However, device B exhibits the matched plasmon–phonon coupling which is aligned with simulation.…”

concentration monitoring. [1] In order to improve sensing accuracy, the engineered photon-electron oscillation resonant along the interface or confined in the subwavelength metamaterial can be utilized. [2] This collective electromagnetic oscillating behavior known as plasmonic resonance is able to express the unique optical features under different conditions. Among the various types of plasmonic resonances, Fano resonance is characterized by the sharp asymmetric line shape, created by the interference of a narrow discrete state (black or subradiant mode) with the broadband continuum state (bright or super-radiant mode) and is favorable for constructing slow light or nonlinear optical platform to launch the high-Q enhanced applications, such as biochemical sensing. [3][4][5][6] The most popular approach to the excitation of Fano resonance in the mid-infrared frequency range is to break the symmetry of metamaterial geometry. [7][8][9] There are other methods including the multistacking of thin metal and dielectric layers [10] and making use of material intrinsic damping as the subradiant mode. [11][12][13] For example, with the mid-infrared vibrational absorption resonance (phonon band) of silicon dioxide as the dark mode, the strong Fano coupling between the SiO 2 thin film and metamaterial split ring resonator (SRR) is observed such that it leads to mode splitting featured as frequency anticrossing. [13] In the asymmetric SRR metamaterial, polymethyl-methacrylate (PMMA) produced Fano resonance is enhanced as well. [14] The Fano resonance from metamaterial plasmon coupled with the phonon vibration of PMMA is varied through changing metamaterial geometry. [11,15] Moreover, the realization of the ultrasensitive detection of polymer molecule is obtained through matching the polymer phonon resonance with the Fano resonance of periodic nanostructures. [16] The alteration of Fano resonance can be achieved by the individual or simultaneous control of dark and bright resonance. The aforementioned geometry variation of subwavelength metamaterial can be used to shift the broad bright mode resonance. The alternative approaches such as mechanical stress, [17] liquid crystal, [18] micro electromechanical system technology [19] are exploited to either modify the optical properties of the surrounding material or actively reconfigure the structure. Recently, the dynamic manipulation of Fano resonance by graphene electrostatic tuning has been demonstrated by some groups. [20,21] Metamaterial-based plasmonics has become an overwhelming research field due to its enormous potential and versatility in molecular sensing, imaging, and nonlinear optics. This work presents a new tunable plasmonic platform on which the metamaterial resonance is coupled with infrared vibrational bond in the presence of graphene electrostatic modulation. The maximum electric field enhancement factor induced by mode coupling is 14 and the quality factor (Q-factor) of phonon mode is increased approximately by fourfold. The graphene electrostatic modulation b...

Nanophotonics, manipulating light-matter interactions at the nanoscale, is an appealing technology for diversified biochemical and physical sensing applications. Guided-wave nanophotonics paves the way to miniaturize the sensors and realize on-chip integration of various photonic components, so as to realize chip-scale sensing systems for the future realization of the Internet of Things which requires the deployment of numerous sensor nodes. Starting from the popular CMOS-compatible silicon nanophotonics in the infrared, many infrared guided-wave nanophotonic sensors have been developed, showing the advantages of high sensitivity, low limit of detection, low crosstalk, strong detection multiplexing capability, immunity to electromagnetic interference, small footprint and low cost. In this review, we provide an overview of the recent progress of research on infrared guided-wave nanophotonic sensors. The sensor configurations, sensing mechanisms, sensing performances, performance improvement strategies, and system integrations are described. Future development directions are also proposed to overcome current technological obstacles toward industrialization.

Tunable metamaterial devices have experienced explosive growth in the past decades, driving the traditional electromagnetic (EM) devices to evolve into diversified functionalities by manipulating EM properties such as amplitude, frequency, phase, polarization, and propagation direction. However, one of the bottlenecks of these rapidly developed metamaterials technologies is limited tunability caused by the intrinsic frequency‐dependent property of exotic tunable material. To overcome such limitation, the microelectromechanical system (MEMS) enabling micro/nanoscale manipulation is developed to actively control “meta‐atom” in terahertz and infrared region, which brings frequency‐scalable tunability and complementary metal‐oxide‐semiconductor‐compatible functional meta‐devices. Beyond tunability, novel chemical sensing platforms of molecular identification and dynamic monitoring of the biochemical process can be achieved by integrating micro/nanofluidics channels with metamaterial resonators. Additionally, incorporating metamaterial absorbers with MEMS resonators brings another research interest in MEMS zero‐power devices and radiation sensors. Furthermore, moving from 2D metasurfaces to 3D metamaterials, enhanced EM properties like novel resonance mode, giant chirality, and 3D manipulation reinforce the application in biochemical and physical sensors as well as functional meta‐devices, paving the way to realize multi‐functional sensing and signal processing on a hybrid smart‐sensor microsystem for booming healthcare, environmental monitoring, and the Internet of Things applications.
