Abstract: An organic thin film includes an organic crystalline phase, where the organic crystalline phase defines a surface having a surface roughness (Ra) of less than approximately 10 micrometers over an area of at least approximately 1 cm2. The organic thin film may be manufactured from an organic precursor and a non-volatile medium material that is configured to mediate the surface roughness of the organic crystalline phase during crystal nucleation and growth. The thin film may be formed using a suitably shaped mold, for example, and the non-volatile medium material may be disposed between a layer of the organic precursor and the mold during processing.

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.
