Implementation of Reservoir Computing Using Coupled Microelectromechanical Drum Resonators via Sideband-Pumped Phonon-Cavity Dynamics
Theresa Farah, Loïc Flis, Pierre Laly +6
Reservoir computing is a bio-inspired machine learning paradigm that exploits the intrinsic dynamics of nonlinear systems with fading memory for efficient temporal information proc…
Wavelength dependence of laser-induced nanowelded microstructures assembled from metal nanoparticles
Ariel Rogers, Isabelle I. Niyonshuti, Jun Ou +3
Light-based nanowelding of metallic nanoparticles is of particular interest because it provides convenient and controlled means for the conversion of nanoparticles into microstruct…
Photonic Metamaterial Analogue of a Continuous Time Crystal
Tongjun Liu, Jun-Yu Ou, Kevin F. MacDonald +1
Time crystals are an eagerly sought phase of matter with broken time-translation symmetry. Quantum time crystals with discretely broken time-translation symmetry have been demonstr…
Ballistic Dynamics of Flexural Thermal Movements in a Nano-membrane Revealed with Subatomic Resolution
Tongjun Liu, Jun-Yu Ou, Nikitas Papasimakis +3
Flexural oscillations of free-standing films, nano-membranes and nano-wires are attracting growing attention for their importance to the thermal, electrical and mechanical properti…
Picophotonics -- Subatomic Optical Localization Beyond Thermal Fluctuations
Tongjun Liu, Cheng-Hung Chi, Jun-Yu Ou +4
Despite recent tremendous progress in optical imaging and metrology, the resolution gap between atomic scale transmission electron microscopy and optical techniques has not been cl…
Volatile optical bistability enabled by mechanical nonlinearity
Dimitrios Papas, Jun-Yu Ou, Eric Plum +1
Optical devices with metastable states controlled with light (optical flip-flops) are needed in data storage, signal processing and displays. Although non-volatile optical memory r…
Engineering the Collapse of Lifetime Distribution of Nitrogen-Vacancy Centers in Nanodiamonds
Hao Li, Jun-Yu Ou, Behrad Gholipour +4
We demonstrate experimentally that the distribution of the decay rates of nitrogen-vacancy centers in diamond becomes narrower by over five times for nanodiamonds embedded in thin…
Decay rate enhancement of diamond NV-centers on diamond thin films
Hao Li, Jun-Yu Ou, Vassili A. Fedotov +1
We demonstrate experimentally two-fold enhancement of the decay rate of NV centers on diamond/Si substrate as opposed to a bare Si substrate. We link the decay enhancement to t…
Hyperspectral Nanomotion Microscopy
Tongjun Liu, Jun-Yu Ou, Kevin F. MacDonald +1
We have developed a technique that extends static scanning electron microscopic imaging to include hyperspectral mapping of fast thermal and externally-driven movements at up to Me…
Deeply Subwavelength Optical Imaging
Tanchao Pu, Jun-Yu Ou, Nikitas Papasimakis +1
We report the experimental demonstration of deeply subwavelength far-field optical imaging of unlabelled samples with resolution better than . We beat the ~/2 diffraction…
Nano-optomechanical Nonlinear Dielectric Metamaterials
Artemios Karvounis, Jun-Yu Ou, Weiping Wu +2
By harnessing the resonant nature of localized electromagnetic modes in a nanostructured silicon membrane, an all-dielectric metamaterial can act as nonlinear medium at optical tel…
Modulating light with light via giant nano-opto-mechanical nonlinearity of plasmonic metamaterial
Jun-Yu Ou, Eric Plum, Jianfa Zhang +1
From the demonstration of saturable absorption by Vavilow and Levshin in 1926, and with invention of the laser, unavailability of strongly nonlinear materials was a key obstacle fo…
Ultrafast all-optical switching via coherent modulation of metamaterial absorption
Xu Fang, Ming Lun Tseng, Jun-Yu Ou +3
We report on the demonstration of a femtosecond all-optical modulator providing, without nonlinearity and therefore at arbitrarily low intensity, ultrafast light-by-light control.…
Ultraviolet and visible range plasmonics of a topological insulator
Jun-Yu Ou, Jin-Kyu So, Giorgio Adamo +3
The development of metamaterials, data processing circuits and sensors for the visible and UV parts of the spectrum is hampered by the lack of low-loss media supporting plasmonic e…
Controlling the Colour of Metals: Intaglio and Bas-Relief Metamaterials
Jianfa Zhang, Jun-Yu Ou, Nikitas Papasimakis +3
The fabrication of indented ('intaglio') or raised ('bas-relief') sub-wavelength metamaterial patterns on a metal surface provides a mechanism for changing and controlling the colo…
Multi-fold Enhancement of Quantum Dot Luminescence in a Plasmonic Metamaterial
K. Tanaka, E. Plum, J. Y. Ou +2
We report that hybridizing semiconductor quantum dots with plasmonic metamaterial leads to a multi-fold intensity increase and narrowing of their photoluminescence spectrum. The lu…
