  By altering the polarization, phase and amplitude at the exit pupil, the
intensity distribution near the focal plane of a Solid Immersion Lens(SIL)
system can be changed. We have studied how the resolution and focal depth
changes for a few particular cases. It was seen that by impinging radial
polarization on a SIL system, we may obtain a rotational symmetric z-component
of the focused wavefront with spot size similar to that predicted by scalar
theory. We also found that it was possible to 'play' with the the contributions
from the homogeneous and inhomogeneous waves behind the SIL by changing the
amplitude and phase distribution at the aperture.
