Abstract: A method of forming a high voltage optical transformer includes forming a via through a transparent carrier wafer, forming a conductive layer within the via, bonding a solid state lighting (SSL) package to a first side of the carrier wafer, and bonding a photovoltaic (PV) wafer to a second side of the carrier wafer opposite to the first side. The photovoltaic wafer may include an active area and a conductive area located outside of the active area that is in electrical contact with the conductive layer. The method further includes forming both an SSL contact with the solid state lighting package and a PV contact with the conductive layer on the same side of the carrier wafer.

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. An applied voltage may be used to control the refractive index of the OSC material and accordingly tune the operation of the optical diffraction grating.

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: 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: A lighting assembly may include a light source and a reflective polarizer overlapping the light source. A portion of light that is incident on the reflective polarizer may not pass through the reflective polarizer and may be reflected back to the light source. The light source may include at least one of a light emitting diode (LED), a micro-LED, an organic light emitting diode (OLED), a micro-OLED, a liquid crystal on silicon (LCoS), or an fLCoS light source. The reflective polarizer may include a polymer birefringent multilayer structure of alternating first layers and second layers. The first layers may each include an isotropic polymer thin film the second layers each include an anisotropic polymer thin film. Various other devices, systems, and methods are also disclosed.
