A non-invasive scattering compensation method, termed F-SHARP, gives direct access to the phase and amplitude of the electric-field point spread function, enabling fast and high-resolution correction of aberrations and scattering in living tissue.
The theoretical study of a 3D photonic topological metacrystal based on an all-dielectric metamaterial platform shows robust propagation of surface states along 2D domain walls, making it a promising solution for photonics applications. The proposed metacrystal design might also open the way for the observation of elusive fundamental physical phenomena.
A regular stream of single photons is generated from a terrylene molecule. The metallodielectric planar antenna, applied to a terrylene molecule, and the optical excitation scheme are developed to achieve intensity fluctuations 40% below the sub-shot-noise limit.
A negatively charged nitrogen–vacancy centre — a promising quantum light source — is created in diamond by laser writing (with pulses with a central wavelength of 790 nm and duration of 300 fs) with an accuracy of 200 nm in the transverse plane.
Experimental data supported by simulations indicate that the trajectories of relativistic electron bunches can be controlled at the attosecond timescale by precise adjustment of the relative phase in a two-colour field scheme. An enhancement in the harmonic yield is also reported.
A tunable photonic microwave filter is monolithically integrated in an InP chip. The filter includes all of the required elements — a laser, a modulator and a photodetector — and its response can be tuned by controlling the electric currents.
A fingertip-sized on-chip optomechanical device offers a controllable way to shift the frequency of single photons in the telecom band while preserving their quantum information.
The combination of whispering-gallery-mode sensing with photothermal absorption spectroscopy promises significant advances in single-molecule identification.
Research groups around the world are rushing to combine perovskites with silicon or other materials in an attempt to make tandem solar cells that promise unprecedented device efficiencies.
Optical clocks with a record low zero-dead-time instability of 6 × 10–17 at 1 second are demonstrated in two cold-ytterbium systems. The two systems are interrogated by a shared optical local oscillator to nearly eliminate the Dick effect.
