ABSTRACT:
An extremely high resolution holographic lens is provided, comprising an interference pattern between light emitted from at least one tiny point source of light such as the tip of an optical fiber, having a diameter in the nanoscale region, and at least one plane or quasi-plane broad light beam. The holographic lens is employed for example in pickups for reading data off of, and writing data upon terabit optical storage mediums and nanoscale resolution microscopic media.
