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.
We report optically-generated focused ultrasound for non-invasive brain stimulation with ultrahigh precision of 83 µm, which is two orders of magnitude smaller than that of conventional transcranial focused ultrasound.
We present experimentally unsupervised learned deconvolution for light-sheet microscopy using propagation-invariant beams. By training a generative adversarial network using simulated paired images consistent with the physics of the imaging system, and real unpaired experimental data, we create a network that can rapidly and robustly deconvolve microscopy images encoded by a complex point-spread function, such as from Airy or Bessel beams. The method is facile and does not need data for training outwith that obtained during conventional imaging.
Two-dimensional photonic crystal phosphor is upgraded in terms of both material and structure, which results in ~7 times enhanced color conversion efficiency compared with reference phosphor.
A semi-nonlinear waveguide in etchless silicon nitride/lithium niobate thin film based on bound states in the continuum achieves high-efficiency second harmonic generation.
Topological insulator metamaterials bring nonlinear terahertz photonic technology a step closer by producing a third-harmonic output power close to a milliwatt.
This paper reviews the fabrication and functionalities of high-refractive-index-contrast optical structures that can serve as versatile optical platforms to address the limitations of current optoelectronic devices.
Graphene and topological insulators are promising platforms for near-field nanotechnology on a subwavelength scale. Authors present the highly confined nature of Dirac plasmon-polaritons in graphene, topological insulator, and hybrid systems.
Afterglow luminescent particles of ZnS:Ag,Co are developed as an efficient light delivery agent for photochemical tissue bonding in deep tissues with prolonged luminescence.
Ions in mixed halide perovskite migrate to the non-illuminated region to form a macroscopic ring structure under laser irradiation, which is reversible after removing the light.
CIOMP report their progress in high-accuracy manufacturing of the world’s largest SiC aspheric mirror. The final surface figure error is 15.2 nm RMS and aerial density is less than 120 kg/m2.
We show that the photon dynamics and lifetimes in asymmetric optical microcavities are greatly modified if the cavity is constructed in a topologically curved space.
Cholesteric Spherical Reflectors (CSRs) are omnidirectional retroreflectors that are selective in circular polarization and wavelength, enabling human-invisible fiducial markers for applications in robotics, augmented reality, anti-counterfeiting, circular economy and more
