Abstract
A method for producing subwavelength near-field optical apertures includes directing a laser beam at the top of a tapered optical fiber to melt the fiber tip. The melting forms a lens at the tip, and the resulting structure is then coated with metal in such a way that an aperture is left open, or the aperture is formed in the metal by means of an ion beam or a laser beam. In another embodiment, the tip of a micropipette is melted by a laser beam to form an aperture having thick walls.
