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: A notched filter includes a multilayer having alternating first and second polymer layers, the first polymer layers each including an isotropic polymer thin film having in-plane refractive indices n1x and n1y, and the second polymer layers each including an isotropic or anisotropic polymer thin film having in-plane refractive indices n2x and n2y, where a thickness of each successive first polymer layer decreases with increasing distance from a centerline of the multilayer, and a thickness of each successive second polymer layer increases with increasing distance from the centerline. Such a filter may be configured to reflect incident light having a desired polarization state within a predetermined and relatively narrow band.

Abstract: An optical element includes a waveguide body that is configured to guide light by total internal reflection from an input end to an output end, an input coupling structure located at the input end for coupling light into the waveguide body, and an output coupling structure located at the output end for coupling light out of the waveguide body, where the waveguide body includes a layer of an optically anisotropic organic solid crystal. Such an optical element may have low weight and exhibit good color uniformity while presenting a 2D diagonal field-of-view of at least approximately 10°.
