Abstract
The polaritons in a two-dimensional artificial ionic-type crystal have been proposed and experimentally demonstrated from the two-dimensional periodically poled LiTaO3. In this artificially micro-structured materials, the anisotropic piezoelectric coefficients and the two-dimensional symmetric result in strong and complex couplings of the incident electromagnetic waves and the two-dimensional superlattice vibrations. We studied the dielectric anomalies, the coupling and transforming between two ordinary polariton modes etc., which reveal that, by engineering the ferroelectric domain’s distribution, the artificial ionic-type crystal may establish a new member of meta-materials, and will facilitate access to the device applications such as multi-directional and frequency transducers.
