A single two-terminal opto-sensor based on multilayer γ-InSe flakes was developed and successfully emulated human-eye-like adaptation behaviors, which could motivate the further development of advanced opto-sensors and artificial visual systems.
Based on the configurable circular-polarization-dependent optoelectronic silent state, our integrated circular polarization detector achieves a near-infinite circular polarization extinction ratio and an ultralow noise equivalent light ellipticity difference of 0.009° Hz−1/2.
Luminescent lanthanide cerium(III) and europium(II) complexes with d-f transition characteristic were demonstrated as new emitters for efficient and color-stable single-emitting-layer white organic light-emitting diodes.
A 2D Dirac cone photonic system with inhomogeneous effective mass gives rise to an in-plane synthetic magnetic field, inducing chiral zeroth Landau levels with one-way propagative characteristics.
Investigation of the spectral narrowing physics of self-injection-locked on-chip lasers to Hz-level linewidth using a composite-cavity structure. Heterogeneously integrated III–V/SiN lasers operating with quantum-dot and quantum-well active regions are analyzed.
A ring resonator is under dynamical modulation. The applied modulation signal includes multiple frequency components. By measuring the transmission spectrum, we are able to resolve the full band structure of a multi-dimensional synthetic lattice.
We propose an on-chip spectrometer design that leverages reconfigurable networks with distributed broadband filters, demonstrating a 30 pm resolution over a 115 nm bandwidth that can be readily scaled further.
Monodisperse high-performance scintillating microcubes consisting of copper-iodide clusters were developed for creating a flexible X-ray imaging screen suitable for static and dynamic settings when doped into a polymer matrix.
This paper demonstrates a 53 km free-space-optical communication link mimicking a satellite-downlink. It achieves 1Tbit/s transmission by addressing turbulence and low-SNR issues through adaptive optics and a novel four-dimensional modulation format.
We propose and demonstrate a metasurface-embedded LCoS device that achieves polarization-independent phase modulation at telecommunication wavelengths with 4K resolution and beyond.
X-ray self-focusing sources are demonstrated by free electrons coherently interacting with van der Waals heterostructures, bypassing the need for X-ray optics that are often inefficient and challenging to fabricate.
The quasi PT-symmetry design enables the creation of electrically pumped large-area edge-emitting lasers with high power single-mode emissions by selectively inducing loss on high-order modes.
Fluorescence-guided bond-selective intensity diffraction tomography is demonstrated to enable 3D hyperspectral chemical cellular imaging, site-specific mid-infrared spectroscopy, and 3D visualization of intracellular tau protein aggregates.
Topological bulk BICs in the vicinity of inverted photonic band edges enable an electrically pumped, compact, single-mode, and beam engineered QCL to be operated at terahertz region.
