Abstract
An optical tip for a Near-field Scanning Optical Microscope (NSOM) is provided. The optical tip includes a waveguide with a semiconductor or metal core and a cladding. The refractive-index-square-ratio contrast between the core and the cladding is at least 0.3. The optical tip may also include a light detector and a light source. The waveguide, the light source and the light detector may be integrated to form a single chip.
