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 fluidic optical element includes a fluid bilayer having a first fluid layer and a second fluid layer defining a fluid interface therebetween, and an electrode disposed over a surface of the fluid bilayer. The geometry of the fluid interface and hence the optical response of the fluid bilayer to incident light may be manipulated using the principle of dielectrophoresis.

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.
