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.

Active modulation of the refractive index in photonic integrated circuits via charge injection

A multilayer organic thin film includes a plurality of biaxially-oriented layers, where each layer is characterized by mutually orthogonal refractive indices, n≠n≠n. In example structures, the corresponding in-plane refractive indices of adjacent layers may be rotated with respect to each other by a predetermined angle. Such a multilayer may be incorporated into a circular reflective polarizer, for example, which may be used in display systems to provide high broadband efficiency and high off-axis contrast. In an example process, individual organic thin films may be molded, and then oriented and stacked to form a multilayer.

Multilayer organic solid thin films having a biaxial refractive index

A system comprising (1) at least one optical element having a nonplanar surface, (2) at least one photonic integrated circuit disposed on the nonplanar surface of the optical element, the photonic integrated circuit comprising (A) an optical core that contains an optically anisotropic organic material and (B) a cladding disposed over the optical core. Various other apparatuses, systems, and methods are also disclosed.

Apparatus, system, and method for disposing photonic integrated circuits on surfaces

A method of forming an organic solid crystal (OSC) thin film includes forming a layer of a non-volatile medium material over a surface of a mold, forming a layer of a molecular feedstock over a surface of the non-volatile medium material, the molecular feedstock including an organic solid crystal precursor, forming crystal nuclei from the organic solid crystal precursor, and growing the crystal nuclei to form the organic solid crystal thin film. An organic solid crystal (OSC) thin film may include a biaxially-oriented organic solid crystal layer having mutually orthogonal refractive indices, n≠n≠n.
