    Abstract: Methods for patterning a metal over a substrate and devices formed using the methods are disclosed. A patterned die having at least one raised portion and having a metal layer over the die is pressed onto a thin metal film over a substrate, such that the metal layer over the raised portion of the patterned die contacts portions of the thin metal film. Pressure is then applied such that the metal layer and the thin metal film cold-weld to one another. The patterned die is removed, such that the portions of the metal layer cold-welded to the thin metal film break away from the die and remain cold-welded to the thin metal film over the substrate, in substantially the same pattern as the patterned die.

    Abstract: A modulated laser device comprising two or more vertically stacked asymmetric waveguides is provided. The laser device comprises a first waveguide having a gain region formed therein for amplifying at least a first mode of light, and a second waveguide vertically coupled to the first waveguide and having a modulator formed therein for modulating a second mode of light having an effective index of refraction different from the first mode. Light propagating in the first waveguide is transferred into the second waveguide via a lateral taper in the first waveguide. The laser device may further comprise a third waveguide positioned between the first and second waveguide for providing isolation between the gain region and modulator. Distributed bragg reflector (DBR) and distributed feedback (DFB) laser designs may be employed in the device.

    Abstract: A method for tuning the wavelength of light emitted by an organic light emitting device. An emissive dopant molecule is selected, adapted to emit light when present as a dopant in an emissive layer of the organic light emitting device. The wavelength of light emitted by said emissive dopant molecule depends on the local dipole moment of the emissive layer. The local dipole moment of the emissive layer that would result in said emissive dopant molecule emitting a desired wavelength of light is determined, and an emissive layer is fabricated, doped with the emissive dopant molecule and having the local dipole moment that results in the emissive dopant molecule emitting the desired wavelength of light.
