Single-particle double-modulation absorption spectrometers based on whispering-gallery-mode microresonators achieve sub-100-Hz sensitivity to photothermal resonance shifts and allow for the study of arrays of Fano resonances in the context of plasmonic–photonic hybridization.
An optomechanical single-photon frequency shifter is demonstrated in integrated AlN waveguides. A frequency shift up to 150 GHz is achieved at telecom wavelength. The device shows near-unity efficiency and preserves the quantum coherence.
Polarization-entangled photons are generated from light-emitting diodes based on site-controlled pyramidal quantum dots. Selective current injection into the vicinity of a quantum dot becomes possible owing to a self-assembled vertical quantum wire.
A new scheme for multicolour X-ray free-electron lasers at soft X-ray wavelengths is proposed. The scheme significantly improves two-colour pulse generation and makes possible the first demonstration of three-colour pulse generation.
The protein crystal growth mechanism can be changed from planar 2D nucleation growth to spiral growth by femtosecond laser ablation. By using this method, the growth rate of a hen egg-white lysozyme crystal increases from 0.3 µm per day to 3.4 µm per day.
An epi-illumination system based on microlens arrays enables field-independent imaging of multiple cells with nanoscale resolution and large field of views.
Coherent mechanical oscillations are optically driven on a metamaterial absorber that has a voltage-tunable Fano resonance. Inversely, optical damping of the mechanical resonance is also achieved.
Non-thermal ultrafast switching of the magnetization in TmFeO3 is demonstrated. Few-cycle terahertz pulses modify the magnetic anisotropy of the ordered Fe3+ spins and trigger nonlinear excitation of the amplitude of spin oscillations.
A terahertz (THz) optical single-sideband modulator (OSSB) for direct conversion of free-space THz electromagnetic radiation to THz optical modulations is realized. The THz OSSB operates in the 0.3–1.0 THz range without any frequency-dependent tuning.
Single photons are generated from electrically driven semiconducting single-walled carbon nanotubes embedded in a photonic circuit. Pronounced antibunching is observed when photon correlation is measured at cryogenic temperatures.
The first field test of quantum teleportation is implemented over a 30 km optical fibre network with independent quantum light sources. To establish a robust quantum teleportation system in the real world, several feedback mechanisms are developed.
Carrier-envelope-phase control of the electronic current over a laterally confined tunnelling gap a few nanometres wide yields current densities above 50 MA cm–2 driven by picojoule-level optical pulses at room temperature.
The first field test of quantum teleportation is implemented across a metropolitan fibre network with independent quantum light sources. To establish a robust quantum teleportation system in the real world, several feedback mechanisms are developed.
Single zinc and mecury ions are optically detected in solution by detuning of metal nanorod resonators coupled to the whispering gallery mode of a dielectric cavity.
Non-magnetic non-reciprocal transparency and amplification is experimentally achieved by optomechanics using a whispering-gallery microresonator. The idea may lead to integrated all-optical isolators or non-reciprocal phase shifters.
