3D metal freeform micromanufacturing

Yves Bellouard, Cyril Dénéréaz, Andreas Mortensen, Raphaël Charvet, Léa Deillon, Sacha Jérémy Florentin Pollonghini, Fatmah Ebrahim, Tao Yang, Enrico Casamenti, Luciano Borasi

Despite remarkable progress made in recent years, producing freeform three-dimensional micro-components out of copper, silver or gold and their alloys remains an engineering challenge: current processes are either too slow to be economically viable, or pro ...

Vibration monitoring based on optical sensing of mechanical nonlinearities in glass suspended waveguides

Yves Bellouard, Tao Yang, Pieter Vlugter, Enrico Casamenti

Vibration monitoring plays a key role in numerous applications, including machinerypredictive maintenance, shock detection, space applications, packaging-integrity monitoring andmining. Here, we investigate mechanical nonlinearities inherently present in s ...

Ablation in Externally Applied Electric and Magnetic Fields

Yves Bellouard, Tao Yang

To harness light-matter interactions at the nano-/micro-scale, better tools for control must be developed. Here, it is shown that by applying an external electric and/or magnetic field, ablation of Si and glass under ultra-short (sub-1 ps) laser pulse irra ...

Observation of e(+) e(-) -> gamma chi(c1) and search for e(+) e(-) -> gamma chi(c0), gamma chi(c2), and gamma eta(c) at root s near 10.6 GeV at Belle

Roberto Gargiani, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Hiroyasu Yamamoto, Timothy Chi Hin Liew, Yong Chan Choi, Seyed Sina Mirrazavi Salehian, Arnaud Michel Gelb, Tao Yang, Gaétan Charles Antoine Giriat, Jun Yong Kim, Linlin Cao, Jiayun Shen, Donghyun Kim, Martin Lubej, Chang-Hyun Park, Lei Li, Ji Hyun Kim, Yiming Li, Xiao Wang

Using data samples of 89.5 fb(-1), 711.0 fb(-1), and 121.4 fb(-1) collected with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider at center-of-mass energies 10.52, 10.58, and 10.867 GeV, respectively, we study the exclusive reactions e(+) ...

Measurement of the branching fraction and time-dependent CP asymmetry for B-0 -> J/psi pi(0) decays

Roberto Gargiani, Olivier Schneider, Sun Hee Kim, Tagir Aushev, Mingkui Wang, Chao Wang, Taoufiq Harach, Yong Chan Choi, Arnaud Michel Gelb, Tao Yang, Gaétan Charles Antoine Giriat, Mithilesh Nayak, Linlin Cao, Jiayun Shen, Donghyun Kim, Lei Li, Yiming Li, Xiao Wang

We measure the branching fraction and time-dependent CP-violating asymmetry for B-0 -> /psi pi(0) decays using a data sample of 711 fb(-1) collected on the Gamma(4S) resonance by the Belle experiment running at the KEKB e(+)e(-) collider. The branching fra ...

Laser-Induced Transition between Nonlinear and Linear Resonant Behaviors of a Micromechanical Oscillator

Yves Bellouard, Tao Yang

We investigate both theoretically and experimentally a laser-based controlled tuning of the nonlinear behaviors of a single mechanical resonator. Thanks to localized three-dimensional modifications induced by femtosecond-laser irradiation, a Duffing-like o ...

Progress on femtosecond laser-based system-materials: three-dimensional monolithic electrostatic micro-actuator for optomechanics

Yves Bellouard, Tao Yang

Femtosecond laser-dielectric interaction in a three-dimensional (3D) manner defines a capable platform for integrated 3D micro-devices fabricated out of a single piece of system-material. Here, we add a new function to femtosecond laser-based single monoli ...

Monolithic transparent 3D dielectrophoretic micro-actuator fabricated by femtosecond laser

Yves Bellouard, Tao Yang

We demonstrate a three-dimensional (3D) monolithic micro-actuator fabricated by non-ablative femtosecond laser micromachining and subsequent chemical etching. The actuating principle is based on dielectrophoresis. An analytical modeling of this actuation s ...
