Abstract

A device includes a pair of electrodes and a dynamic material disposed between the pair of electrodes, the dynamic material including a crystalline microstructure configured to change between at least two states in response to a change in an electric field between the two electrodes. A material includes tetragonal lead magnesium niobate-lead titanate (PMN-PT) and at least one lanthanide series element. A method includes doping a lead magnesium niobate-lead titanate material with at least one lanthanide series element, and processing the PMN-PT material to form tetragonal PMN-PT. A further method includes forming a low refractive index nanostructured grating over a carrier substrate, forming a high refractive index layer over the low refractive index grating to produce a nanostructured coupling element, forming an adhesive layer over the nanostructured coupling element, and affixing the nanostructured coupling element to a high index waveguide.
