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 ...
EPFL2024Transition to chaos in extended systems and their quantum impurity models
Chaos sets a fundamental limit to quantum-information processing schemes. We study the onset of chaos in spatially extended quantum many-body systems that are relevant to quantum optical devices. We consider an extended version of the Tavis-Cummings model ...
Bristol2024Thermo-optic epsilon-near-zero effects
Camille Sophie Brès, Marco Clementi, Jiaye Wu, Qian Li
Nonlinear epsilon-near-zero (ENZ) nanodevices featuring vanishing permittivity and CMOS-compatibility are attractive solutions for large-scale-integrated systems-on-chips. Such confined systems with unavoidable heat generation impose critical challenges fo ...
Berlin2024Antenna-coupled infrared nanospectroscopy of intramolecular vibrational interaction
Hatice Altug, Aurélian Michel John-Herpin, Felipe Herrera
Many photonic and electronic molecular properties, as well as chemical and biochemical reactivities are controlled by fast intramolecular vibrational energy redistribution (IVR). This fundamental ultrafast process limits coherence time in applications from ...
Washington2023Imaging and controlling coherent phonon wave packets in single graphene nanoribbons
The motion of atoms is at the heart of any chemical or structural transformation in molecules and materials. Upon activation of this motion by an external source, several (usually many) vibrational modes can be coherently coupled, thus facilitating the che ...
NATURE PORTFOLIO2023Nonlocally-resonant metamaterials
In this thesis, we unveil a third design path to manipulate elastic waves within architected media, distinct from the traditional phononic crystal and locally-resonant metamaterial concepts. The core innovation lies in the concept of nonlocal resonances, d ...
EPFL2023Voltage-tunable optical parametric oscillator with an alternating dispersion dimer integrated on a chip
Tobias Kippenberg, Anton Stroganov, Aleksandr Tusnin, Alexey Tikan
Optical parametric oscillators enable the conversion of pump light to new frequency bands using nonlinear optical processes. Recent advances in integrated nonlinear photonics have led to the creation of compact, chip-scale sources via Kerr-nonlinearity-ind ...
Washington2023van der Waals Materials for Overcoming Fundamental Limitations in Photonic Integrated Circuitry
With the advance of on-chip nanophotonics, there is a high demand for high-refractive-index and low-loss materials. Currently, this technology is dominated by silicon, but van der Waals (vdW) materials with a high refractive index can offer a very advanced ...
AMER CHEMICAL SOC2023Characterization of two electronic subsystems in cuprates through optical conductivity
Understanding the physical properties of unconventional superconductors as well as of other correlated materials presents a formidable challenge. Their unusual evolution with doping, frequency, and temperature has frequently led to non-Fermi-liquid (non-FL ...
2023Photonic assembly tunable via the pockels effect and method for use in frequency-modulated lidar
Tobias Kippenberg, Viacheslav Snigirev, Grigorii Likhachev
A photonic assembly, a laser setup comprising said photonic assembly and a method for performing frequency-modulated continuous-wave light detection and ranging using said laser setup are disclosed. The photonic assembly (1) comprises an active photonic ch ...
