Abstract: LIGHT WAVEGUIDE WITH A SUBMICRON APERTURE, METHOD FOR MANUFACTURING THE WAVEGUIDE AND APPLICATION OF THE WAVEGUIDE IN AN OPTICAL MEMORY The light waveguide consists of an optically transparent body at one end cut to a sharp tip and polished optically flat at the other. A metallization on its surface is thick enough to be opaque. By pressing the waveguide against a rigid plate, the metallization is plastically deformed so as to expose a tiny aperture at the tip of the body through which light can pass. By carefully controlling the deformation of the metallization, the diameter of the aperture can be kept between 10 and 500 nm. The application of the aperture when incorporated in the semiconductor laser of the read/write head of an optical storage device is described.
