Holography recording properties of new dye-doped ionic liquid crystals for using in optical switch applications

摘要

For the first time the multi-gratings holographic recording has been obtained in novel class of liquid crystals namely in ionic lyotropic metal-organic smectics formed on the base of metal alkanoates. It was shown that alkali metal alkanoates form smectic structures. They self-organized in hydrophobic bi-layers of alkanoate chaines with electrostatic conductive layers. The gratings are recorded by the action of pulsed laser radiation both picosecond and nanosecond duration from double frequency Nd-YAG laser. The multi-gratings formation can be connected with the recording process in micro-domains of smectic matrix.
