“…[22] In addition, the response of this device does not stem from the melting-solidification transition that deforms the integrity of the design, so it provides a stable and extendable platform for efficient thermal-optical device designs such as optical modulators, optical switches, and optical modulators. [7,8] In conclusion, we analyzed and experimentally confirmed the unprecedented thermo-optical sensitivity of an MM MPA that is entirely made of Bi. To fabricate this sample, oblique angle deposition is utilized not only as a lithography-free and a large-scale compatible route, but also to achieve a scaffold that efficiently confines and harvests the MIR radiation with a spectrally selective resonant response.…”

Efficient confinement and harvesting of the electromagnetic (EM) radiation is one of the most vigorously studied research areas under metamaterials, due to their vast variety of applications. [1][2][3] These attractive properties are, nevertheless, acquired by the periodic arrangement of subwavelength material dimensions and, therefore, functional optical devices require complex fabrication routes, such as electron beam lithography (EBL). Moreover, dynamic control of these optical properties is another issue that has attracted much attention in recent years. To attain the possibility of real-time tuning of the EM response of the metadevices, dynamically tunable scenarios are needed. Several techniques, such as electrical, [4] optical, [5] and thermal [6] tuning, have been proposed in the literature to realize active tunable metamaterials.The class of thermally tunable metamaterial perfect absorbers (MPAs) are emerging as promising candidates in the applications of optical modulators and infrared camouflage. [7,8] Their operation principle lies in the thermo-optical effect of the change in the optical constants of a material with temperature, [9] which is prominent in the phase-change materials, such as GeSbTe (GST) and vanadium dioxide (VO 2 ) as well as amorphous silicon. [10][11][12] Thermally tunable MPAs need to fulfill the requirements of high sensitivity, spectrally selectivity, and low-power dissipation. This makes low-melting-point metals, such as bismuth (Bi), zinc (Zn), gallium (Ga), lead (Pb), and tin (Sn), candidates for such applications. [13] Therefore, taking all of this into account, the large-scale realization of MPAs is crucial for their mass-production with high-throughput as well as repeatability. [14] Zhao et al. reported a linearly thermal-tunable ultra-narrowband MPA based on four-nanorod (NR)-coupled amorphous silicon with a sensitivity of 0.08 nm C À1 . [11] They revealed that the shift in the resonance wavelength from 1164 to 1172 nm proportionally increasing temperature depends on the change of the optical constants. However, the proposed design is not large-scale compatible as well as findings are numerical based.Among the aforementioned low-melting-point materials cited herein, Bi is a low-toxicity, low-cost, earth-abundant heavy element with a melting point of 271.3 C. [15] In its solid bulk state, Bi presents semimetallic properties. The real part of the dielectric permittivity of solid Bi from ultraviolet to near-infrared spectral ranges presents negative values. [16,17] In this spectral range, the liquid phase Bi is a Drude metal with strong losses, [18] and thus a "lossy" plasmonic material. Bi nanoparticles (NPs), embedded

Evolving from metamaterials, optical metasurfaces not only inherit their unprecedented flexibility in tailoring light–matter interaction but also the generally fixed response determined by the metaatoms' geometries—an undesirable property that hinders the development of practical metadevices. Consequently, novel optical metasurfaces that can be tuned in an active manner are intensively studied in recent years. Due to their optically thin structures, optical metasurfaces present unique characteristics in the realization of dynamic tuning. In this review, a detailed summary of the recent advances in active optical metasurfaces is provided including discussions reviewing a variety of active materials and approaches that enable faster, stronger, and more accurate tuning. Beyond facilitating practical metadevices, studies of active metasurfaces have, and will continue to deepen the understandings of the interaction between light and nanostructured photonic architectures and to promote the development of nanofabrication techniques involving high‐complexity.
