Abstract: 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, n1≠n2≠n3.

Abstract: An organic thin film includes an organic solid crystal material and has mutually orthogonal refractive indices, nx, ny, and nz each having a value at 589 nm of between approximately 1.5 and approximately 2.6, where nx≠ny≠nz. The organic thin film may be birefringent, and may be configured as a single layer thin film, or plural organic thin films may be stacked to form a multilayer that may be incorporated into an optical element, such as a reflective polarizer.
