Photonics offers high hopes for next-generation neural network processors. Now it has been shown that even entirely using off-the-shelf photonics allows surpassing speed and energy efficiency of cutting-edge GPUs.
Progress in the field of quantum-photonics applications of metasurfaces is reviewed. Cutting-edge research, including the development of optical chips supporting high-dimensional quantum entanglement and advanced quantum tomography, is summarized.
Optical acoustic sensors have gained interest for use in photoacoustic imaging systems, but can they dethrone conventional piezoelectric sensors altogether?
Recent effort in controlling the structure of light in all its degrees of freedom and dimensions has pushed the limits of structured light and broadened its potential beyond orbital angular momentum, two-dimensional fields, qubits and biphotons, and linear optical manipulation.
Laser-like radiation with a very large spectral coverage is obtained with a comb-like spectrum by concatenating nonlinear processes. Such a light source is extremely useful for detecting molecular trace gases.
More atoms can not only absorb more light but, if prepared in a particular quantum state, can also do so faster than single atoms. Now, researchers have experimentally demonstrated this time-reversed process of superradiance.
A new paradigm is emerging in which molecular properties are controlled by modifying the local electromagnetic environment, rather than the traditional approach of changing their composition or structure. Now, a tool to investigate such effects has been demonstrated that should accelerate progress in this exciting field.
Two independent studies employing the same narrowband deep-blue emitter, ν-DABNA, but different energy transfer schemes, achieve efficient and stable deep-blue electroluminescence.
A network of quantum sensors for estimating phase shifts is shown to operate with superior sensitivity when delocalized highly entangled states are employed.
A method to quantitatively map transient electromagnetic waveforms with atomic-spatial resolution is now possible using lightwave-driven scanning tunnelling microscopy featuring a single-molecule switch.
Photonics offers an attractive platform for implementing neuromorphic computing due to its low latency, multiplexing capabilities and integrated on-chip technology.
This Review covers the milestones for extreme-ultraviolet frequency combs and their applications. A future impact on the construction of nuclear-based optical clocks and multidimensional attosecond photoelectron spectroscopy of solids is remarked.
Electromagnetic fields in light waves are mainly transverse to propagation direction but actually also have longitudinal components, which may give rise to unexpected optical phenomena involving the angular momentum of light, such as transverse spin and optical torques.
Scintillators used in X-ray detectors typically require the use of heavy metal atoms to efficiently harvest ionizing radiation. Now the use of halogens is shown to yield efficient, metal-free organic scintillators.
