Three-dimensional nonlinear optical metamaterials are realized by directly engineering the symmetries of electronic wavefunctions at the atomic scale by stacking individual two-dimensional van der Waals interfaces into a precisely designed three-dimensional configuration.
Vladimir Zakharov was a man of a strong passion and grand intellect, who was equally and deservedly proud of both his scientific achievements and his poetry.
We posit that inconsistent interpretations of experimental data have led to inaccurate claims on metalens focusing efficiencies. By performing a meta-analysis, we show that extraordinary claims of high focusing efficiency at high numerical apertures are, unfortunately, not yet backed by rigorous simulation or experimental results.
A scheme for fast, comprehensive characterization of high-dimensional quantum states could aid quantum applications in imaging and information processing.
Allen Weeks, Director General of the Extreme Light Infrastructure European Research Infrastructure Consortium, talks to Nature Photonics about the founding and future of the high-power-laser facilities, and stimulating a resurgence of physics in new EU member countries.
Combining photoacoustic excitation with optomechanics enables the mechanical modes associated with entire microorganisms to be detected, demonstrating that mechanical spectroscopy allows us to identify microorganisms and characterize their life stages.
New conductive and perovskite inks enable hand-drawing of optoelectronic devices with a ballpoint pen on a variety of daily substrates, including paper, textiles and other irregular surfaces.
Photonics enables the design of ultrafast, energy-efficient computing approaches for artificial intelligence, and key to the scalability of such approaches is photonics integration.
Since the inception of the idea of temporal solitons in optical fibres, published in 1973, the concept of optical solitons has revolutionized the fundamental science of optics and photonics technologies. This Perspective gives an outlook on the future of solitons in ultrafast lasers, frequency combs, biomedical applications, telecommunications and signal processing, as well as the emerging new science of solitons.
Event-based detectors, which respond to local changes in light intensity rather than producing images, enable super-resolution single-molecule localization microscopy with sensitivity and resolution comparable to conventional methods.
A mid-infrared dual-comb system capable of nanosecond time-resolved spectral measurements is realized by using a singly resonant optical parametric oscillator that allows an efficient conversion of an input dual-comb pump at 1 µm into an idler dual comb in the mid-infrared regime.
Event-based sensors enable super-resolution single-molecule localization microscopy with comparable quality and resolution to traditional scientific cameras, while also overcoming the limitations of high-density imaging.
Radio-frequency modulation of optical signals increase the parallelization of photonic processors beyond that afforded by exploiting spatial and wavelength dimensions alone. The approach is then demonstrated on electrocardiogram signals and identifies patients at sudden death risk with 93.5% accuracy.
A cascaded hard X-ray self-seeding system is demonstrated at the European X-ray free-electron laser. The setup enables millijoule-level pulses in the photon energy range of 6–14 keV at the rate of ten trains per second, with each train including hundreds of pulses arriving at a megahertz repetition rate.
