Our work is a combination of nanotechnology and optics — we research ways in which control light on a length scale smaller than its wavelength. Due to the diffraction limit, light is difficult control once this fundamental barrier is reached; but there are ways around it, using the peculiar optical properties of small metallic nanostructures, which show an extraordinarily strong interaction with light.
Over the last year we have become particularly interested in how these electromagnetic modes on metallic nanoparticles lead to vibrations of the particle, due to decay of the electronic excitation into lattice vibrations. Coupling between electromagnetic and mechanical modes of nanostructures might open new avenues for the development of highly integrated optical devices.
