Room-Temperature Quantum Optomechanics and Free-Electron Quantum Optics

Quantum optics studies how photons interact with other forms of matter, the understanding of which was crucial for the development of quantum mechanics as a whole. Starting from the photoelectric effect, the quantum property of light has led to the develop ...

The physics of 3D printing with light

Christophe Moser

The goal of 3D printing is to realize complex 3D structures by locally adding material in small volume elements called voxels - in contrast to successively subtracting material by etching, milling or machining. This field started with optics-based proposal ...

Physics of optically driven nanojunctions

Philippe Andreas Rölli

Recent years have seen spectacular developments in the domain of nano-optics. Alongside the well-known techniques of super-resolution microscopy progress in nanofabrication has enabled important improvements in the fields of optical imaging and spectros ...

Floquet dynamics in the quantum measurement of mechanical motion

Tobias Kippenberg, Nicolas Piro Mastracchio, Liu Qiu, Itay Shomroni, Marie Adrienne Ioannou

The radiation-pressure interaction between one or more laser fields and a mechanical oscillator gives rise to a wide range of phenomena: From sideband cooling and backaction-evading measurements to ponderomotive and mechanical squeezing to entanglement and ...

Virus lasers for biological detection

Gabriel Aeppli

The selective amplification of DNA in the polymerase chain reaction is used to exponentially increase the signal in molecular diagnostics for nucleic acids, but there are no analogous techniques for signal enhancement in clinical tests for proteins or cell ...

Parametric amplification and bidirectional invisibility in PT-symmetric time-Floquet systems

Romain Christophe Rémy Fleury, Theodoros Koutserimpas

Parity-time (PT)-symmetric wave devices, which exploit balanced interactions between material gain and loss, exhibit extraordinary properties, including lasing and flux-conserving scattering processes. In a seemingly different research field, periodically ...

Appearance and Disappearance of Quantum Correlations in Measurement-Based Feedback Control of a Mechanical Oscillator

Tobias Kippenberg, Dalziel Joseph Wilson, Sergey Fedorov, Ryan Daniel Schilling, Vivishek Sudhir, Amir Hossein Ghadimi

Quantum correlations between imprecision and backaction are a hallmark of continuous linear measurements. Here, we study how measurement-based feedback can be used to improve the visibility of quantum correlations due to the interaction of a laser field wi ...

Observation of the hyperfine spectrum of antihydrogen

Shirit Cohen

The observation of hyperfine structure in atomic hydrogen by Rabi and co-workers(1-3) and the measurement(4) of the zero-field ground-state splitting at the level of seven parts in 10(13) are important achievements of mid-twentieth-century physics. The wor ...

A 1.5-W frequency-doubled semiconductor disk laser tunable over 40 nm at around 745 nm

Elyahou Kapon, Vladimir Iakovlev, Alexei Sirbu

We report on a semiconductor disk laser emitting 1.5 W of output power at the wavelength of 745 nm via intracavity frequency doubling. The high power level and the >40 nm tuning range make the laser a promising tool for medical treatments that rely on phot ...

Experimental verification of the method for producing a three-dimensional cross-pairs metamaterial structure based on a dielectric AlN cube

Przemyslaw Andrzej Gorski

This paper presents a method of manufacturing 3D metamaterial structures using laser radiation. Our proposed material, aluminum nitride (AlN), by interaction of a high-energy laser beam undergoes a direct metallization process, a result of which a conducti ...
