Objective of the joint research should be the understanding of the
dynamics of the imaging process in near field optics. Emphasis should be put
on identifying the key physical aspects which determine resolution,
usability and time resolution. Time resolved SNOM measurements and a colour
SNOM will be used.

Objective of the joined research should be the development of nanometric
structures with specifically designed far-field and near-field optical
properties and corresponding far- and near-field optical methods for their
investigation. Theoretical models should be developed in order to calculate
the optical response of the structure and the influence of the measuring

Objective of the joint research should be the "nanowriting" of
lines on ferroelectric surfaces and the detection of these ones. We could
use the SNOM fibre tip as a nanoscopic light source and the capability of
the microscope to obtain shear force topographical images to detect these
lines. In order to improve the size resolution we will also utilise other
techniques such as AFM and SEM. Using physical properties of ferroelectric
used in these experiments we can develop a possible device without
connections. Additionally, theoretical simulations will test previous
theories and will be used to include new image reconstruction techniques in

Objective of the joint research will be a model study of the imaging
process with apertureless techniques, and the read-out process of optical disk
storage: correlation between signal and topography, or groove profile and
position. Also, influence of groove defects on the read-out signal.

The present project is intended to push the effort of
understanding the basic mechanisms underlying near-field optical technology.
Major progress has been made on the experimental set-ups.
Yet, several ideas and concepts have been taken for granted. Recently,
artefacts have been demonstrated. It is necessary to re-examine any
component of the set-ups and to this aim, a basic understanding of the
physics is necessary.
Particular issues are :
The investigation of the different feed-back
controls and their implications on the image formation.
Is it possible to suppress artefacts due to
feedback control ?
What are the resolution limits ?
Is it possible to analyse theoretically the
potential performances of the different set-ups ?
Implications of reciprocity in near-field.
Is it possible to define a transfer function
for illumination SNOM ?
To what extent the inverse problem can be
solved in illumination SNOM ?
What are the optimal working conditions ? (coherence,
angles of detection, polarisation, etc.)
The above program is the necessary work to attack on a
firm basis the problem of designing systems with good resolutions for e.g.

Objective of the joint research is the development of a faster tip-sample
distance control in SNOM for data storage applications. The achieved
bandwidth will be assessed by means of test samples produced in the
framework of the project, whereas read/write rate will be tested by means of
suitable ferroelectric thin films produced by Pulsed Laser Deposition (PLD)
or provided by other partners of the project. Optimal wavelength for the
read/write process will be determined on different ferroelectric materials.
