“…Furthermore, the changes of the THz quantum vacuum induced by a perfectly reflecting plate or by a plate possessing a surface plasmon polariton were studied in this configuration [9]. Options to sample not only the electric component of the propagating quantum field but also its second generalized conjugated quadrature [10,11] have been discovered recently [12,13], paving the way towards a new type of quantum tomography operating completely in the time domain. In general, these subcycle studies of quantum fields are exploring deep connections between quantum and relativistic physics [11,14], thus creating a new platform for future advances in this frontier region of contemporary science.…”

Terahertz (THz) radiation encompasses a wide spectral range within the electromagnetic spectrum that extends from microwaves to the far infrared (100 GHz to ~30 THz). Within its frequency boundaries exist a broad variety of scientific disciplines that have presented, and continue to present, technical challenges to researchers. During the past 50 years, for instance, the demands of the scientific community have substantially evolved and with a need for advanced instrumentation to support radio astronomy, Earth observation, weather forecasting, security imaging, telecommunications, non-destructive device testing and much more. Furthermore, applications have required an emergence of technology from the laboratory environment to production-scale supply and in-the-field deployments ranging from harsh ground-based locations to deep space. In addressing these requirements, the research and development community has advanced related technology and bridged the transition between electronics and photonics that high frequency operation demands. The multidisciplinary nature of THz work was our stimulus for creating the 2017 THz Science and Technology Roadmap (S S Dhillon et al 2017 J. Phys. D: Appl. Phys. 50 043001). As one might envisage, though, there remains much to explore both scientifically and technically and the field has continued to develop and expand rapidly. It is timely, therefore, to revise our previous roadmap and in this 2023 version we both provide an update on key developments in established technical areas that have important scientific and public benefit, and highlight new and emerging areas that show particular promise. The developments that we describe thus span from fundamental scientific research, such as THz astronomy and the emergent area of THz quantum optics, to highly applied and commercially and societally impactful subjects that include 6G THz communications, medical imaging, and climate monitoring and prediction.

“…Using a detection geometry with a more broadband frequency response (i.e., with thinner detection crystals and/or longer gate-pulse wavelengths), in order for the EOS trace to resemble the MIR field more closely, this stability benefits the sensitive time-domain investigation of nonlinear effects [16,18,159,160]. For our experimental setup, a further reduction of the fluctuations would require a lower RIN of the laser frontend or a compression scheme with taylored noise characteristics for a reduction of the amplitude noise [161]. For a shot-noise limited laser oscillator output, the timing and amplitude jitter values are expected to be ≈ 3 orders of magnitude lower than the fluctuations measured here.…”
