Five-step fabrication method of a pencil-shaped fiber probe with a protrusion from a metal film and near-field optical image of 20nm-gold particles illuminated by a 488nm argon ion laser. The authors propose a method to fabricate a probe with nanometric protrusion for near-field optical microscopy. [See article by Shuji Mononobe, R. Uma Maheswari and Motoichi Ohtsu for details.]
