Coherent ultra-violet to near-infrared generation in silica ridge waveguides
Nature Communications, 2017 Continuum generation in optical fibres has enabled many applications, like optical frequency combs. Here, Ohet al. demonstrate controlled dispersive-wave generation in on-chip silica waveguides, which could have a similar impact on integrated devices.

Time-Frequency Analysis and PDE's
, 2008 We study the action on modulation spaces of Fourier multipliers with symbols $e^{imu(xi)}$, for real-valued functions $mu$ having unbounded second derivatives. We show that if $mu$ satisfies the usual symbol estimates of order $alphageq2$, or if $mu$ is a positively homogeneous function of degree $alpha$, the corresponding Fourier multiplier is ...

Quantum Flows for Secret Key Distribution in the Presence of the Photon Number Splitting Attack
Entropy, 2014 Physical implementations of quantum key distribution (QKD) protocols, like the Bennett-Brassard (BB84), are forced to use attenuated coherent quantum states, because the sources of single photon states are not functional yet for QKD applications. However,

Time-Frequency Synthesis and Filtering
, 2016 This chapter presents methods and techniques to design time-varying linear systems such as filters with precise time-frequency (t, f) specifications; this capability can then allow one to model and predict accurately the effects of linear systems on nonstationary signals in applications such as signal cleansing and enhancement. This topic is covered in

Characterization of Power-to-Phase Conversion in High-Speed P-I-N Photodiodes
IEEE Photonics Journal, 2011 Fluctuations of the optical power incident on a photodiode can be converted into phase fluctuations of the resulting electronic signal due to nonlinear saturation in the semiconductor.

Frontiers in Astronomy and Space SciencesIntroductionGeomagnetic storms are typical solar eruption activities. When high-speed solar wind or coronal mass ejections from solar eruptions strike the Earth, they trigger rapid severe geomagnetic disturbances and further induce ionospheric variations.

Versatile laser-free trapped-ion entangling gates
New Journal of Physics, 2019 We present a general theory for laser-free entangling gates with trapped-ion hyperfine qubits, using either static or oscillating magnetic-field gradients combined with a pair of uniform microwave fields symmetrically detuned about the qubit frequency ...
