Ultra-broadband Terahertz spectroscopy with Terahertz air photonics
, 2016 Terahertz (THz) spectroscopy is a well-established technique which allows for measuring the complex-valued dielectric properties of materials, specifically semiconductors, in the THz range. As THz photons have a low energy, typically comparable to intraband transitions, they are ideal probes of important phenomena such as the momentum relaxation of ...

Laser &Photonics Reviews, EarlyView.An etchless lithium niobate (LN) metasurface with a slanted periodic TiO2 grating enables efficient and narrowband second‐harmonic generation (SHG) thanks to the light confinement in the LN film granted by quasi‐bound‐state‐in‐the‐continuum (q‐BIC) modes.

Predicting Statistical Signatures of Collective Emission in Disordered Color Center Ensembles
Laser &Photonics Reviews, EarlyView.We present an efficient simulation framework for modeling collective emission in disordered ensembles of quantum emitters. The low computational complexity enables large‐scale Monte Carlo simulations. Applied to SiV−${\rm SiV}^{-}$ clusters, it predicts thresholded superradiant bursts set by emitter number and quantum efficiency, as well as interaction‐

3D-Printed Quasi-Optics for Sub-Terahertz Range
The high bandwidth available in the terahertz domain is promising for non-destructive evaluation (NDE) and inspection applications. Although 3D-printing offers great flexibility and fast design iteration when developing quasi-optical components for such ...

Tunable Terahertz Generation in Dispersion‐Engineered ZnTe Waveguides
Laser &Photonics Reviews, EarlyView.A dispersion‐engineered Zinc Telluride (ZnTe) slab waveguide platform enables tunable and efficient guided‐wave terahertz (THz) generation through modal phase matching. By tailoring the optical and THz modal dispersion, coherent THz emission is achieved across 0.1–3 THz.

Parallel Multi‐Target Detection for Quantum LiDAR
Laser &Photonics Reviews, EarlyView.Parallel multi‐target detection is achieved in quantum LiDAR with a single‐pixel quantum readout. Direction and distance information are extracted together, allowing multiple objects to be distinguished under noisy low‐light conditions and pointing to a new strategy for scan‐free quantum remote sensing.

Parallel Vector Processing in Optical Computing With Jacobi Time‐Wave Packets
Laser &Photonics Reviews, EarlyView.Functionality of a single neuron and state of the art photonic acceleration with a Mach‐Zehnder‐interferometer (MZI) mesh (i), a crossbar array (ii) and a micro ring resonator (MRR) array (iii). In the proposed Jacobi time‐wave packet approach (iv) a single modulator (here a ring modulator) is performing the whole scalar vector product in a single ...
