Integrated microwave photonics using thin-film lithium niobate on silicon nitride

Lithium niobate (LiNbO3) is a key material in photonics due to its exceptional properties. The linear electro-optic effect, also known as the Pockels effect, in lithium niobate induces a linear change in the refractive index when an electric field is appli ...

Sensitivity and spectral control of network lasers

Alexis Arnaudon

Recently, random lasing in complex networks has shown efficient lasing over more than 50 localised modes, promoted by multiple scattering over the underlying graph. If controlled, these network lasers can lead to fast-switching multifunctional light source ...

Quantum Measurement of Mechanical Motion close to the Standard Quantum Limit

Liu Qiu

In quantum mechanics, the Heisenberg uncertainty principle places a fundamental limit in the measurement precision for certain pairs of physical quantities, such as position and momentum, time and energy or amplitude and phase. Due to the Heisenberg uncert ...

Phase sensitivity in differential phase contrast microscopy: limits and strategies to improve it

Christophe Moser, Timothé Laforest, Mathieu Künzi, Chiara Bonati

The phase sensitivity limit of Differential Phase Contrast (DPC) with partially coherent light is analyzed in details. The parameters to tune phase sensitivity, such as the diameter of illumination, the numerical aperture of the objective, and the noise of ...

Diffractive small angle X-ray scattering imaging for anisotropic structures

Goran Lovric

Insights into the micro- and nano-architecture of materials is crucial for understanding and predicting their macroscopic behaviour. In particular, for emerging applications such as meta-materials, the micrometer scale becomes highly relevant. The micro-ar ...

Kerr Comb-based Transfer Oscillator for Ultralow Noise Photonic Microwave Synthesis

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Romain Dany Bruno Bouchand

We perform optical frequency division of an ultra-stable laser by using a crystalline-based Kerr frequency comb as a transfer oscillator. We demonstrate absolute phase noise levels of -110 dBc/Hz at 200-Hz offset from a 14 GHz carrier. (C) 2019 The Author( ...

Radiation and Internal Loss Engineering of High-Stress Silicon Nitride Nanobeams

Dalziel Joseph Wilson, Amir Hossein Ghadimi

High-stress Si3N4 nanoresonators have become an attractive choice for electro- and optomechanical devices. Membrane resonators can achieve quality factor (Q)frequency (f) products exceeding 10(13) Hz, enabling (in principle) quantum coherent operation at r ...

Quantum cascade laser-based Kerr frequency comb generation

Tobias Kippenberg, Erwan Guillaume Albert Lucas, John David Jost, Clément Christian Javerzac, Caroline Marie Anne Lecaplain

We report mid-infrared Kerr comb generation based on a quantum cascade laser pumping a crystalline microresonator. For the first time QCL light is coupled into a microresonator via a tapered chalcogenide fiber allowing mid-IR Kerr comb generation. ...
