1. A photonic integrated circuit comprising:
an organic solid crystal (OSC) material layer, the OSC material layer comprising a substrate portion and a raised optical element integral with and extending from the substrate portion, wherein the raised optical element is configured to have a pattern reciprocally defined by a patterned electric field applied to an electrically conductive liquid layer adjacent to the OSC material layer.
