    摘要： An asymmetric twin waveguide (ATG) structure with quantum-well intermixing in the taper region of the active waveguide is disclosed. The structure comprises a first waveguide, a second waveguide, and a taper formed in the second waveguide. The taper has an intermixed area formed therein comprising a plurality of quantum wells intermixed with a plurality of barriers. The quantum wells and barriers may be intermixed using plasma-enhanced intermixing such as, for example, Argon plasma enhanced intermixing. Quantum-well intermixing reduces absorption loss normally encountered in the movement of light between waveguides.

    摘要： A structure is provided that includes an aperiodic dielectric stack. The structure may include a substrate, a device disposed over the substrate, and a first dielectric stack disposed between the substrate and the device. The first dielectric stack includes a plurality of layers comprising a first dielectric material, wherein at least two of the layers comprising a first dielectric material have substantially different thicknesses, as well as a plurality of layers comprising a second dielectric material. The average outcoupling efficiency into air of the device over a bandwidth of at least 300 nm may be at least 40% greater than that of an otherwise identical device disposed in a structure without the first dielectric stack.

    摘要： A device is provided. The device includes a base, and a reservoir disposed in the base. The reservoir is defined by a cladding and the base, and has an opening with a largest dimension of about 200 nm or less, more preferably 100 nm or less, and most preferably 60 nm or less. A material may be disposed within the reservoir. The base may be attached to a position control apparatus that may control the position of the base with an accuracy on the order of nanometers. The position control apparatus may include an atomic force microsope and/or a near field scanning optical microscope. The base may also be coupled to an energy application apparatus that may apply energy to the material. The device may be used to deposit material onto a substrate with a very high resolution, on the order of a few molecules across. The device may also be used to remove material from a substrate with a very high resolution by transmitting energy through the base. A device used for such removal may or may not include a reservoir.

    摘要： An asymmetric twin waveguide (ATG) structure is disclosed that significantly reduces the negative effects of inter-modal interference in symmetric twin-waveguide structures and which can be effectively used to implement a variety of optical devices. The ATG structure of the invention can be monolithically fabricated on a single epitaxial structure without the necessity of epitaxial re-growth. To achieve the ATG structure of the invention, the effective index of the passive waveguide in the ATG is varied from that of a symmetric twin waveguide such that one mode of the even and odd modes of propagation is primarily confined to the passive waveguide and the other to the active waveguide. The different effective indices of the two coupled waveguides result in the even and odd modes becoming highly asymmetric. As a result, the mode with the larger confinement factor in the active waveguide experiences higher gain and becomes dominant. In a further embodiment, the active waveguide is tapered to reduce coupling losses of the optical energy between the passive waveguide and the active waveguide. In a further embodiment, a grating region is incorporated atop the passive waveguide to select certain frequencies for transmission of light through the passive waveguide.

    摘要： A method of depositing organic material is provided. A carrier gas carrying an organic material is ejected from a nozzle at a flow velocity that is at least 10% of the thermal velocity of the carrier gas, such that the organic material is deposited onto a substrate. In some embodiments, the dynamic pressure in a region between the nozzle and the substrate surrounding the carrier gas is at least 1 Torr, and more preferably 10 Torr, during the ejection. In some embodiments, a guard flow is provided around the carrier gas. In some embodiments, the background pressure is at least about 10e-3 Torr, more preferably about 0.1 Torr, more preferably about 1 Torr, more preferably about 10 Torr, more preferably about 100 Torr, and most preferably about 760 Torr. A device is also provided. The device includes a nozzle, which further includes a nozzle tube having a first exhaust aperture and a first gas inlet; and a jacket surrounding the nozzle tube, the jacket having a second exhaust aperture and a second gas inlet. The second exhaust aperture completely surrounds the first tube aperture. A carrier gas source and an organic source vessel may be connected to the first gas inlet. A guard flow gas source may be connected to the second gas inlet. The device may include an array of such nozzles.
