DETECTION OF MELAMINE IN PACKAGING MATERIALS USING TERAHERTZ TIME-DOMAIN SPECTROSCOPY

Química Nova
To detect melamine in packaging materials, terahertz time-domain spectroscopy (THz-TDS) was employed to measure the terahertz absorption spectra of melamine-polyethylene mixtures with varying mass ratios (1:0-3).

Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics

Laser &Photonics Reviews, EarlyView.
All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...

Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication

Laser &Photonics Reviews, EarlyView.
A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

Mode‐Locked Pulse Generation in Plasmonic Lattices

Laser &Photonics Reviews, EarlyView.
The plasmonic superlattices overlaid with optically pumped organic molecules produce multimode lasing due to mid‐range radiative coupling (MR‐RC, lambda) and long‐range radiative coupling (LR‐RC, 10 lambda). Right: The mode locking emerges spontaneously due to the shared excited state molecular populations which may emit photons to various different ...
