Optical Method to Modify Nanostructures
Scientists at a New York University have recently announced the development of a new optical technology, which allows them to use a tiny beam of light in order to move nanostructures. The beam employs as little as one milliwatt of power in order to do this, but it can move structures that are about 12 nanometers in diameter, which is a rather large size. The structure's optical properties can be fundamentally altered as well, the team reports, saying that the silicon structures can be made from transparent to opaque, and vice-versa. The team's new achievement could be used to create advanced micro-electromechanical systems (MEMS) in the near future. MEMS are nothing more than devices featuring moving parts, but at the nanoscale. The construction of micro-optomechanical systems (MOMS) could also become a lot easier. These systems also include photonic circuits in addition to the moving parts. The new research could be used, for instance, to create a tunable filter to pass one particular optical wavelength, which may be of tremendous use in a number of applications, but especially in microscopy and in telescope-based studies. The technique could also be used to develop a method of turning light moving through a nanostructure "on" or "off," by modifying the shape of the structure. This will most likely be heavily used in new MEMS and MOMS devices.
