The observation of a room-temperature stable liquid phase of electrons and holes in a quasi-two-dimensional photocell paves the way towards optoelectronic devices that harness collective phenomena.
The cost of infrared detectors has limited the deployment of multispectral imagers and sensors. Researchers now demonstrate simple quantum-dot devices that promise fast, sensitive and low-cost cameras that can switch between short- and mid-wavelength infrared.
A type of near-field curved light field generated right at the output of a dielectric cuboid is experimentally observed. It is expected to have interesting applications in imaging and manipulation.
By tailoring the anisotropy of light scattering along the surface of a macroscopic flat object, mechanical stabilization can be achieved without focused incident light or excessive constraints on the shape, size or material composition of the object.
This Review covers recent progress in AlGaN-based deep-ultraviolet light-emitting devices. The key technologies of how to improve their performance, carrier-injection efficiency, light extraction efficiency and heat dissipation are discussed.
Low-cost spectroscopy, mobile phone-based imaging and laser-processed paper sensors are all examples of how photonics could help tackle India’s healthcare and environmental monitoring challenges.
Orbital angular momentum is a property of light that has many emerging applications, but has been poorly appreciated until recently. The wavelength frontier of orbital angular momentum sources is extending beyond the ultraviolet thanks to research in fields ranging from nanostructures to free-electron lasers.
Propagating on fibre links between multiple nodes of a network, light gets trapped by multi-path interference and forms complex states that are very sensitive to external perturbations. Now, a network of subwavelength, doped polymer fibres has been shown to operate as a network laser.
Frequency comb spectroscopy is a recent field of research that has blossomed in the past five years. This Review discusses developments in the emerging and rapidly advancing field of atomic and molecular broadband spectroscopy with frequency combs.
This Review discusses the developments and applications of on-chip optical frequency comb generation based on two concepts—supercontinuum generation in photonic-chip waveguides and Kerr-comb generation in microresonators.
This Review describes quantum frequency combs that operate via photon entanglement, beginning with mode-locked quantum frequency combs followed by energy–time entanglement methods. The use of photonic integration and fibre-optic telecommunications components in enabling the quantum state control are also discussed.
Integrated photonics could allow for the generation, manipulation and detection of quantum light on-chip, opening the path to a scalable, reliable platform for real-world deployment of quantum applications.
The demonstration of Pr3+-doped phosphors that exhibit persistent luminescence in the UVC region when exposed to X-rays not only expands the scope of afterglow phosphors, but also offers new opportunities for sensing and biomedicine.
Quantum correlations from photon antibunching enhance the resolution of image scanning microscopy in biological imaging by twofold, four times beyond the diffraction limit.
This Review discusses recent advances of microwave photonic technologies and their applications in communications and information processing, as well as their potential implementations in quantum and neuromorphic photonics.
Using a single atom in a cavity to control a propagating optical pulse can deterministically create a Schrödinger-cat state — an intriguing quantum superposition of classically distinct states. The result is a new opportunity for quantum state engineering with potential applications in quantum networks and computation.
