Superresolution Optical Pick-Up Using Phase Pupil Filter With a Solid Immersion Lens
B Veerappa, Xiao Tang
Superresolution phase pupil filter in conjunction with solid immersion lens for high density in optical data storage is described. The frequency response of the system is studied. A binary annular phase filter is used in this study. Simulation results are included to show the effectiveness of using such a system with acceptable side lobe effect.
