Full optical type optical element

摘要

A full optical type optical element performs an information processing on an input signal light beam (1) through use of only light beams including the signal light beam (1) and an auxiliary light beam (2) for assisting operation. The optical element includes aggregates (3) which are dispersed within the optical element as optical functional aggregates, and which are composed of a single kind or multiple kinds of compounds including a single species of atoms or molecules. Thus, a full optical type optical element having a high resolution can be obtained through use of a thin-film element which contains nanoparticles comprising molecules of an organic compound and associates/aggregates of these molecules. <IMAGE>
