]]> 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 up to microwave rates. There is no feedback or externally-applied modulation in the experiment and the optical input is continuous. Microwave-rate oscillations build-up from an inherent parametric process. This is therefore both a spectroscopic technique and a micro-mechanical device.
As reported by Carmon, T. and Vahala, K. in PRL

]]> Atomic Force Microscopy (AFM) is an important tool for nanotechnology. We tried to use more interesting and interactive way to demonstrate how AFM works. We build a hand held optical lever model (called AFM education kit) that allows people use this model to scan a nanostructure model. A powerful device, WiiTM-mote controller (NintendoTM) is used in the AFM education kit. Wiimote combines infrared camera, MEMS (Micro-Electro-Mechanical Systems) acceleration sensors and Bluetooth connection. The motion of the AFM education kit is captured by Wiimote. Here two infrared light sources act as the reference and a wireless (Bluetooth) connection sends the signals to a notebook,
