Paper Abstract

The optical system in recordable optical disc must satisfy both a reduction in spot size for a high data capacity, and an increase in optical energy for high data transfer rate. We have devised one simple optical element that converts the Gaussian intensity distribution into the flat intensity distribution by refraction without optical energy loss or aberrations.
