Floquet phonon lasing in multimode optomechanical systems

Laura Mercadé, Karl Pelka, Roel Burgwal +3

Dynamical radiation pressure effects in cavity optomechanical systems give rise to self-sustained oscillations or `phonon lasing' behavior, producing stable oscillators up to GHz f…

Vertical engineering for large stimulated Brillouin scattering in unreleased silicon-based waveguides

Laura Mercadé, Alexander V. Korovin, Yan Pennec +2

Strong acousto-optic interaction in silicon-based waveguides generally requires releasing of the silicon core to avoid mechanical leakage into the underlying silica substrate. This…

Lateral forces on nanoparticles near a surface under circularly-polarized plane-wave illumination

Francisco J. Rodríguez-Fortuño, Alejandro Martínez, Nader Engheta +1

Optical forces allow manipulation of small particles and control of nanophotonic structures with light beams. Here, we describe a counter-intuitive lateral optical force acting on…
