Optomechanical GHz Oscillator and Spectroscopy. Just like the spectral signature of materials originates from molecular vibrations, photonic devices have many spectral lines originating from their different mechanical modes. Our group has excited these modes using the radiation pressure produced by light circulating within the device (1, 2, 3) which oscillate regeneratively at controllable mechanical eigen-frequencies [...]

Here we see how an electrical field applied by light can compress material to excite mechanical vibration. We replace metal electrodes with the electrical field that light applies to create a train of virtual electrodes that are almost exactly 250 nm apart. These virtual electrodes act collectivity to excite a mechanical mode, illustrated above, that [...]
