Increased data storage in optical data storage and retrieval systems using blue lasers and/or plasmon lenses |
摘要 |
A optical recording medium (10) includes a crystallizing layer (7,8) for enhancing the crystallization of a phase change memory layer (3), an energy storage layer for aiding the state transformations of a phase change memory layer (3), and/or a modifying element for increasing absorption and contrast at short wavelengths. An optical data storage and retrieval system ( figure 3 ) containing same. A light-plasmon coupling lens including an optically transparent substrate having a light incident surface and a light-plasmon coupling surface opposite the light incident surface. The light-plasmon coupling surface including at least a set of circular concentric peaks/valleys which form a Fourier sinusoidal pattern in the radial direction of the circular concentric peaks/valleys. A conformal layer of metal is deposited on the light-plasmon coupling surface of the substrate and has aperture at the center of thereof through which plasmons are transmitted.
