We present a high-performance integrated platform for broadband active and passive coherent photonics based on planarized THz quantum cascade lasers, featuring low losses and improved dispersion, RF and thermal properties.
To gain an insight into the lattice and band structure of blue perovskite NC emitters, doping organic cations (FA+) reduces nonradiative recombination at room temperature. The FA+ significantly decreases exciton quenching and phonon energy scattering via manipulating hot carriers and electron filling in band structure.
The proposed adaptive-learning framework empowers automatic design of quantum receivers capable of combating noise in distinguishing large-alphabet nonorthogonal quantum states. Experiments show up to 40% improvement over standard approaches.
Boltzmann thermometers rely on the luminescence from energy levels in thermal equilibrium. Understanding of factors that enhance equilibration allows the design of lanthanide-based thermometers with extended operating range.
Highly efficient and stable white LEDs were fabricated based on Eu3+ doped CsxK1-xPbCl3 PeNCs, in which the PeNC film experienced the band engineering and defect passivation treatment.
Holes of 10–30 nm in diameter are produced on sapphire with a depth to width aspect ratio of over 16 and a zero taper with a single pulse longitudinal field.
A transmission-matrix-based framework is proposed to establish the intrinsic link between angular diversity and spatial footprint in multi-channel systems and to derive a bound on the thickness of nonlocal metasurfaces.
Energy-efficient artificial photonic synapse is designed based on photo-sensitive BP/CdS heterostructure device, which can be used for high-performance brain-inspired neuromorphic computing.
The Hatano–Nelson model with asymmetric couplings is demonstrated for the first time in phase locked laser arrays. The arrays exhibit steerable non-Hermitian skin effects.
In this paper, the THz emission properties from Si wafers with different surface conditions and doping conditions have been concluded, which show the potential application of LTEM on surface estimation
We report on a fully hybridized magnetic resonance and optoacoustic tomography (MROT) system for concurrent noninvasive structural and functional imaging of the murine brain.
Schematic diagrams of SD-PQLED based on light interaction layer and light-emitting layer and proof-of-concept diagram of the light interactive display by a four-pixel SD-PQLEDs.
Mechanical bound states in the continuum are observed in an optomechanical microresonator, which open a new way of phonon trapping in micromechanical structures with dissipation channels.
Demonstration of generation of terahertz structured light in a form of configurable Airy beam for imaging aims and 2D materials inspection using exclusively flat silicon diffractive optics.
We developed a new framework in designing centimeter-scale achromatic multi-level diffractive lenses by light frequency-domain coherence optimization, which shows significant advantages in white-light imaging performance over the traditional refractive lens.
