    Abstract: A patterned roller, and a method of making the patterned roller, is provided. A patterned roller may be made by first forming a first mold having a negative pattern by etching pits in a flat mold surface with an etching process. Then, a second mold is formed having a positive pattern, by pouring a first curable material into the first mold, curing the first curable material, and removing the first curable material from the first mold. Then the patterned roller having the negative pattern is formed by coating a roller with a layer of a second curable material, pre-curing the second curable material to provide a viscous but not hardened surface, and rolling the roller over the second mold to create the negative pattern in the second curable material. The second curable material is then cured. Any of the curable materials may be coated after curing, preferably with metal, to reduce sticking in subsequent steps. The patterned roller may be used to create a pattern of microlenses in a third curable material. A substrate is coated with the third curable material. The patterned roller is rolled over the third curable material to transfer the pattern to the third curable material. The third curable material may then be cured.

    Abstract: An OLED may include regions of a mineral having a refractive index less than that of the substrate, 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.

    Abstract: A plurality of quantum dots each have a shell. The quantum dots are embedded in an organic matrix. At least the quantum dots and the organic matrix are photoconductive semiconductors. The shell of each quantum dot is arranged as a tunneling barrier to require a charge carrier (an electron or a hole) at a base of the tunneling barrier in the organic matrix to perform quantum mechanical tunneling to reach the respective quantum dot. A first quantum state in each quantum dot is between a lowest unoccupied molecular orbital (LUMO) and a highest occupied molecular orbital (HOMO) of the organic matrix. Wave functions of the first quantum state of the plurality of quantum dots may overlap to form an intermediate band.

    Abstract: A monolithic wavelength stabilized system comprises a laser monolithically formed with a waveguide splitter having at least two branches. Non-identical resonators having different wavelengths are operatively coupled to each branch of the splitter and a photodiode is communicatively coupled to receive the output from each non-identical resonator. A control unit receives the photocurrent outputs from the photodiodes, determines based on the photocurrents whether the wavelength of the laser signal is at a desired value, and transmits a feedback signal to the laser to move the laser output toward the desired wavelength. The laser, splitter, resonators, and photodiodes are monolithically formed in a single chip using asymmetric waveguides.
