Researchers developed a three-dimensional varifocal meta-device to address AR display challenges, including vergence-accommodation conflict. The device dynamically adjusts focal length and position using tunable metasurfaces, enabling virtual content display at different depths and positions without bulky components.
A new material platform is introduced to overcome limitations of conventional solid-state acousto-optic phase modulators. The polydimethylsiloxane (PDMS) acousto-optic phase modulator enables fourfold increase in phase modulation index and sub-MHz spectral resolution.
Researchers developed an AI-driven super-resolution imaging method called eDL-cSIM, which captures fine cellular details from a single camera exposure. This technique reduces photon dose and frame count by over ninefold, making it suitable for fast and gentle live-cell observation.
This study proposes a non-drug and non-thermal approach to enhance neuronal growth and synaptogenesis using THz photons. The research reveals that specific frequencies of THz photon stimulation increase cAMP levels, which is then mediated by AC1, ultimately promoting synaptogenesis and cognitive improvement.
The Photonics M3 conference focuses on manufacturing, manipulation, and measurement of photonic devices. Key topics include information optics, biomedical optics, meta optics, and advanced optical fabrication. The conference will be held at Tsinghua Southeast Asia Center in Bali, Indonesia.
Researchers have developed a single-fiber linear-cavity laser integrated with multifunctional devices, achieving ultra-high repetition frequencies and acquisition rates. The system leverages harmonic mode-locking to multiply the equivalent Δf_rep and generate GHz-level dual-combs.
Researchers developed a nanoscale antenna using optically levitated nanoparticles, achieving a 10,000-fold reduction in size compared to conventional solutions. This innovation addresses challenges in miniaturizing antennas for critical low-frequency communication scenarios.
Researchers report first experimental observation of Nonlinear Raman-Nath diffraction in a submicron-thick periodically poled lithium niobate thin film. The study investigates the impact of pump wavelength, sample poling period, and incident angle on diffracted beam properties.
A team of scientists developed a new soft microalgae robot (saBOT) using microalga Euglena gracilis as the main body, regulated by a photonic nanojet generated by a TiO2 microsphere lens. The robot demonstrates controllable deformation and precise navigation in complex environments.
Scientists uncover hidden quantum behaviors within classical light, revealing two contrasting behaviors: classical and quantum coherence. This discovery could lead to more robust quantum technologies, mitigating decoherence and accessing quantum properties.
Researchers introduce a novel approach to multiplexed fringe projection profilometry using deep learning and frequency-domain multiplexing. This method achieves high-resolution and high-speed 3D imaging at near-one-order of magnitude-higher frame rates with conventional low-speed cameras.
