Modulated electrooptic response imaging technique

Objective

European experience, American innovations, and Russian physics background are combined in this Project to create a new kind of scanning probe microscopy (SPM). Conventional SPMs address optical properties or tip-surface interaction forces. We propose to implement SPM by introducing raster-scanning measurements of the linear electrooptic effect.

The main goal of this method is to provide nanoscopic scale resolved, topographic artifacts free, order parameter related images of modern complicated materials, including artificial nanostructures. The new experimental tool is expected to keep main advantages of scanning techniques known so far: atomic force microscopy, near-field optical microscopy, and ac field modulation imaging. It will provide European researchers with advanced instrumentation securing leadership in the field of materials science. The proposed new technique is a flexible configuration of independent experimental blocks.

The involved participants have separately tested each of them in previous studies. We estimate scanning near-field optical microscopy to be potentially the most powerful tool to study solid state objects with nanoscopic resolution. We have conceived a set of practical steps to realize this potential. Apertureless near-field scanning optical microscopy (ANSOM) is aimed to achieve ultimate spatial resolution. The modulation approach will drastically enhance the amplitude sensitivity to ensure sufficient signal-to-noise ratio critical for nanoscopic studies.

Finally, replacing the optical index as an output value with the linear electrooptic (or magnetooptic) effect will provide the structure related information. New artificial materials, domain engineered systems, and spatially inhomogeneous phase transitions are the most evident applications of the proposed technique.
