Abstract: A multilayer reflective polarizer includes a layer of a birefringent organic solid crystal, where the birefringent organic solid crystal has a refractive index of at least approximately 1.5 and a birefringence of at least approximately 0.1. The multilayer reflective polarizer may be configured to include alternating layers of a birefringent organic solid crystal material and a secondary material layer selected from an amorphous polymer, an inorganic amorphous compound, a liquid crystal, and an OSC material. The refractive index of the birefringent organic solid crystal layer(s) may be modified through the application of an applied voltage, current, or stress.

Abstract: A birefringent organic thin film includes mutually orthogonal in-plane refractive indices (nx and ny) and a through thickness refractive index (nz), where nx>1.4, ny?1.4, nz>1.4, Dnxy?0.1, Dnxz<0.01, and Dnyz<0.01. Optical properties including refractive index and birefringence may be continuously tuned by applying a voltage across the birefringent organic thin film.

Abstract: An optical diffraction grating includes a layer of organic solid crystal (OSC) material, an input photonic element configured to couple an input beam to the organic solid crystal material, and an output photonic element configured to receive an output beam from the organic solid crystal material.

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 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.
