Nanomodulators of light on optical micro-probes to study the brain (IMAGE)
Caption
A tapered optical fiber equipped with nanostructures that resonate in response to a light stimulus introduced by the fiber itself into deep brain regions. The nanostructures were created by coating the probe microscopic tip with a thin layer of gold. Then, using a gallium ion beam as a chisel, a grid of nanoscopic optical elements (consisting of 100 nm thin lines) was shaped.
