    Ultralow-noise microwave signals are generated at 12 GHz by a low-noise fibre-based frequency comb and cutting-edge photodetection techniques. The microwave signals have a fractional frequency stability below 6.5 × 10–16 at 1 s and a timing noise floor below 41 zs Hz–1/2.

    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.

    Uncompromised performance of micro-optical compound lenses has been achieved by high-fidelity shape definition during two-photon absorption microfabrication. The lenses have been made directly onto image sensors and even onto the tip of an optic fibre.

    Direct f–2f self-referencing of a microresonator-based optical frequency comb is demonstrated at a repetition rate of 16.4 GHz. The carrier envelope offset frequency and repetition rate are stabilized to a hydrogen maser-based atomic clock.

    Mechanical oscillation in a microtoroidal optical cavity transfers chaos from a pump to a probe laser beam with a different wavelength. Through stochastic resonance, the combination of noise and internal chaotic dynamics leads to amplification of optomechanically induced light self-oscillations.

    A photonic analogue of charge pumping in electronic quantum Hall systems is demonstrated by using a finite 2D square annulus of ring resonators. Topological invariants are investigated by observing the shift of the edge state resonances.
