    Abstract: An organic semiconductor device is provided. The device has a first electrode and a second electrode, with an organic semiconductor layer disposed between the first and second electrodes. An electrically conductive grid is disposed within the organic semiconductor layer, which has openings in which the organic semiconductor layer is present. At least one insulating layer is disposed adjacent to the electrically conductive grid, preferably such that the electrically conductive grid is completely separated from the organic semiconductor layer by the insulating layer. Methods of fabricating the device, and the electrically conductive grid in particular, are also provided. In one method, openings are formed in an electrically conductive layer with a patterned die, which is then removed. In another method, an electrically conductive layer and a first insulating layer are etched through the mask to expose portions of a first electrode. In yet another method, a patterned die is pressed into a first organic semiconductor layer to create texture in the surface of the first organic semiconductor layer, and then removed. An electrically conductive material is then deposited onto the first organic semiconductor layer from an angle to form a grid having openings as a result of the textured surface and the angular deposition. In each of the methods, insulating layers are preferably deposited or otherwise formed during the process to completely separate the electrically conductive layer from previously and subsequently deposited organic semiconductor layers.

    Abstract: An OLED may include regions of a material having a refractive index less than that of the substrate, or of the organic region, allowing for emitted light in a waveguide mode to be extracted into air. These regions can be placed adjacent to the emissive regions of an OLED in a direction parallel to the electrodes. The substrate may also be given a nonstandard shape to further improve the conversion of waveguide mode and/or glass mode light to air mode. The outcoupling efficiency of such a device may be up to two to three times the efficiency of a standard OLED. Methods for fabricating such a transparent or top-emitting OLED is also provided.

    Abstract: An optoelectronic device may be fabricated on a three dimensional surface by transferring a material from an elastomeric stamp to a non-planar substrate. The use of an elastomeric stamp allows for patterned layers to be deposited on a non-planar substrate with reduced chance of damage to the patterned layer. The material may be deposited on the stamp while the stamp is in a planar configuration or after the stamp has been deformed to a shape generally the same as the shape of the non-planar substrate. The material may be transferred by cold welding. The device may include organic layers.

    Abstract: An unipolar organic injection laser in which electrically-stimulated intraband transitions result in lasing. An active region includes at least one organic injector layer and at least one organic emitter layer. Each organic emitter layer has a first energy level and a second energy level on a same side of an energy gap defined by a conduction band and a valance band. Charge carriers are injected through the organic injector layer into the first energy level of the organic emitter layer when a voltage is applied across active region. The difference in energy between the first and second energy levels produces radiative emissions when charge carriers transition from the first energy level to the second energy level. Population inversion is maintained between the first and second energy levels, producing stimulated emission and lasing.
