“…Some thermal THz sensors have been reported to achieve ultrahigh sensitivity by cooling to extremely low temperatures to suppress thermal noise. [98][99][100] The detection principles of photonics can be classified into linear and nonlinear responses. In the linear mechanism, sensors are designed to absorb and emit the same energy levels as the THz light using quantum wells and Landau levels.…”

The integration of flexible electronics with optics can help realize a powerful tool that facilitates the creation of a smart society wherein internal evaluations can be easily performed nondestructively from the surface of various objects that is used or encountered in daily lives. Here, organic‐material‐based stretchable optical sensors and imagers that possess both bending capability and rubber‐like elasticity are reviewed. The latest trends in nondestructive evaluation equipment that enable simple on‐site evaluations of health conditions and abnormalities are discussed without subjecting the targeted living bodies and various objects to mechanical stress. Real‐time performance under real‐life conditions is becoming increasingly important for creating smart societies interwoven with optical technologies. In particular, the terahertz (THz)‐wave region offers a substance‐ and state‐specific fingerprint spectrum that enables instantaneous analyses. However, to make THz sensors accessible, the following issues must be addressed: broadband and high‐sensitivity at room temperature, stretchability to follow the surface movements of targets, and digital transformation compatibility. The materials, electronics packaging, and remote imaging systems used to overcome these issues are discussed in detail. Ultimately, stretchable optical sensors and imagers with highly sensitive and broadband THz sensors can facilitate the multifaceted on‐site evaluation of solids, liquids, and gases.

“…The transition edge sensor requires tuning to operate at that particular temperature and requires integrated amplifiers [52]. Recently, a terahertz transition edge sensor has been coupled with a kinetic inductance amplifier (instead of the usual superconducting quantum interference device amplifier) to provide a linear device with high dynamic range operating at 4.2 K. The NEP is ≈ 5 × 10 −14 W Hz −1/2 [53].…”

Physics is the interplay of energy and matter. Energy, in the form of light, interacting with matter, principally in the solid state, underpins this topical review. The subject is developed carefully and methodically, beginning with basic definitions pertaining to terahertz detectors and terahertz radiation, then proceeding systematically to delineate characteristics of terahertz photons and terahertz detectors in more detail. In-between, the intimate connection linking terahertz sensors and terahertz sources is highlighted-an important aspect unfortunately often overlooked or ignored when terahertz detectors are discussed in isolation. At the centre of this topical review are the various physical mechanisms by which electromagnetic radiation of terahertz frequencies interacts with matter. The logic is to present first the underlying physical principles of detection before presenting the practical implementation in a specific device, rather than the other way around. A taxonomy of terahertz detectors is then proposed based on the underlying physical principles of detection. Following on from this classification, stateof-the-art terahertz detectors are surveyed and appraised; this overview constitutes the longest section of the review. Key detector parameters which inform applications are then presented and tabulated. Finally, the present state-of-the-art is anchored within the wider scientific context of historical developments and future prospects.

“…For millimeter and sub-millimeter wave detection, many groups have worked on antenna-coupled micro and nano bolometers, mostly with low T c superconductors [11], [12]. Recently, Kuzmin et al reported an antennacoupled, voltage biased transition edge sensor for 1-6 THz [13], where the superconducting material is 5 nm-thin NbN, and the operating temperature of the device is 4.2 K. Also, Hammer et al [14] reported a THz detector based on spiral antenna coupled YBCO microbolometer with responsivity of 190 V/W across the frequency range of 330 GHz to 1.63 THz. Log-spiral [15], [16], slot antenna [11], and sinuous antenna [17] are different types of antennas which are mostly used in this era.…”

We report on the response of a monolithic high Tc transition-edge bolometer to about 3-mm-wave for the first time. The detector structure consisting of 400 nm YBa2Cu3O7−x (YBCO) film on buffered Yttria Stabilized Zirconia substrate without any coupled antenna, shows bolometric type responsivity to the 3-mm-waves radiation at its transition temperature. The YBCO thin film and Ce0.9La0.1O2 buffer layer are both fabricated by the metal-organic deposition method. The meander line pattern of the bolometer is designed for obtaining maximum absorption and responsivity possible when the polarized radiation of the source is aligned with the pattern. Meander lines are 50 micrometers wide and 1.5 mm long. We have measured amplitude and phase of the response versus modulation frequency of the detector to the linearly polarized 95 GHz source, and the detector was biased at 5 distinct temperatures at the transition corresponding to five different electrical conductivities of the YBCO film. When the meander lines of the device are parallel to the incident beam polarization, the YBCO pattern is speculated to act as a dissipative antenna resulting in higher absorption leading to high magnitude of the response as observed. The results from the measured phase of the response versus modulation frequency are also in agreement with the discussed absorbed mechanism. The absorption of the YBCO pattern is also measured to depend on the electrical conductivity of the YBCO film and our results show that there is an optimum electrical conductivity for having maximum absorption for this detector. Simulation results for this structure confirm the experiments showing that at electrical conductivity value of 1.33 × 10 5 S/m we have the maximum absorption for our device. These observations promise design of versatile THz and millimeter-wave detectors with potentials for applications in medical and security imaging.
