An optical fibre-fed superconducting electro-optic modulator with gigahertz bandwidth and attojoule per bit electric power consumption offers a fast, efficient means to connect superconducting circuits to the room temperature environment.
Ultrasound-induced luminescence in trianthracene derivative-based nanoparticles enables tumour imaging and immunological profiling in a variety of in vivo models.
A non-common-path interferometric scheme enables holographic detection of single proteins of mass 90 kDa and estimation of single-protein polarizability.
The frequency of coherent terahertz waves radiated from a single superconducting emitter can be electronically modulated on a chip with up to 40 GHz bandwidth, paving the way for high-data-rate and ultrafast terahertz wireless communications.
Brillouin light scattering anisotropy microscopy affords single-shot collection of angle-resolved phonon dispersion, enabling the mapping of mechanical anisotropies in living matter with a frequency resolution of 10 MHz and a spatial resolution of 2 µm.
A photonic equivalent to disclination in crystals has been used to produce orbital angular momentum laser light directly on-chip, ushering in compact and efficient twisted-light lasers.
Electrical excitation of a perovskite light-emitting diode is shown to contribute to optical gain, a milestone on the path towards a non-epitaxial laser diode.
The fast response and efficiency of plastic scintillators are severely degraded by the preferential population of slow triplet excited states in luminescence centres, such as in dye molecules. This issue can be solved by hot exciton manipulation, which avoids population of the lowest triplet state.
Nonlinear optical resonators allow the coherent conversion of photons, yet fabrication tolerances limit their wavelength accuracy. Introducing periodic modulation in ring resonators is shown to allow robust and predictable selection of the converted photons.
Acoustic modulation of atmospheric air enables the deflection of laser pulses with a peak power of 20 gigawatts, expanding the acousto-optics toolbox to high-power laser manipulation in ambient air.
A coherent microwave-to-optical conversion scheme, previously feasible only under cryogenic environments, has now been expanded to ambient conditions by using Rydberg atoms.
