摘要：

A novel super-resolution system using a waveguide device is proposed and theoretical considerations are given. This system is capable of raising the storage density of optical discs considerably. The detected signal is calculated using scalar diffraction theory and the three-dimensional beam propagation method. The structure of the disc is substantially the same as that of conventional compact discs, which is the outstanding advantage of this method.
