Abstract: A light-emitting device includes a light-emitting diode having an emissive surface, and a capping layer including an organic solid crystal overlying the emissive surface. The refractive index of the organic solid crystal may be tuned such as through the application of a voltage, current, or stress to improve the light extraction efficiency of the device.

Abstract: An organic field effect transistor includes a channel structure having a photoalignment layer and an organic semiconductor layer disposed directly over the photoalignment layer, where a charge carrier mobility varies along a thickness direction of the channel structure. The channel structure may define an active area between a source and a drain of the transistor and may include alternating layers of at least two photoalignment layers and at least two organic semiconductor layers. Each photoalignment layer is configured to influence an orientation of molecules within an overlying organic semiconductor layer and hence impact the mobility of charge carriers within the device active area while also advantageously decreasing the OFF current of the device.

Abstract: An optical device includes a first polarization selective reflector positioned in a first orientation so that the first polarization selective reflector: receives first light in a first direction; redirects a first portion, of the first light, having a first polarization to a second direction that is non-parallel to the first direction; and receives second light in a third direction and transmit a first portion, of the second light. A second polarization selective reflector positioned in a second orientation non-parallel to the first orientation, and adjacent to the first polarization selective reflector so that the second polarization selective reflector: receives third light in a fourth direction; redirects a first portion, of the third light, having the first polarization to a fifth direction that is non-parallel to the fourth direction; and receives fourth light in a sixth direction and transmit a first portion, of the fourth light having the second polarization.

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.

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.
