ABSTRACT:
The invention provides a method for the production of a photonic device comprising providing a substrate, forming in the substrate substantially straight pores, lining or filling the pores with a material having voltage-dependent index of refraction, and removing part but not all of the substrate materials so that an array remains of tubes or rods of material having voltage-dependent index of refraction. In a variant of the method the deposited material is piezoelectric and the substrate is completely removed, resulting in piezoelectric tubes or rods of small diameter, generally below 10 μm.
