Abstract
A photonic integrated circuit (PIC) includes an organic solid crystal (OSC) material layer, the OSC material layer having a substrate portion and a raised optical element integral with and extending from the substrate portion. The raised optical element may include a passive or active component of the photonic integrated circuit.
Claims18
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.
A device comprising:
- an organic solid crystal (OSC) substrate;
- and
- an optical element disposed over the substrate, wherein the optical element comprises an organic solid crystal layer and is configured to have a pattern reciprocally defined by a patterned electric field applied to an electrically conductive liquid layer adjacent to the OSC substrate.
