摘要： In a laser pulse generator, short pulses adjustable in the range between about 0.1 and 0.5 nanoseconds are produced by improved spectral filtering of the output of a gas breakdown switch. The spectral filter in one embodiment is a hot, linearly absorbing gas cell that passes both sidebands of the radiation producing the gas breakdown in the switch and that linearly absorbs the center frequency. A second embodiment uses a tandem dual-slit monochromator as the spectral filter in order to pass both sidebands. The hot gas cell is simpler, cheaper and characterized by a higher rejection ratio than any other alternative to date. It yields very clean pulses with a steeper leading edge than prior techniques. The leading edge is highly reproducible, as needed for nuclear fusion work. The advantage over prior pulsed CO.sub.2 lasers for nuclear fusion work is substantial, since those prior lasers have not achieved pulse durations less than one nanosecond.

摘要： An omnidirectional optical reflector structure (41, 52, 61) is made by forming a plurality of holes in a solid body (11) so as to result in a face-centered cubic lattice. Conventiently, the desired structure can be made by three successive steps of microfabrication, e.g., in the presence of a mask layer (12). Preferred reflector structures can be used, e.g., as external mirrors as filters, and as cavity materials of communications lasers with improved signal-to-noise ratio.

摘要： In the fabrication of microelectronic, optoelectronic, and photonic devices, methods are being used which involve selective processing of material in the presence of a patterned mask layer; for example, such processing may involve etching. Typically, mask layer material is chosen on the basis of response to suitable radiation, allowing for patterning by selective irradiation followed by selective removal of mask layer material. However, in so-called epitaxial lift-off processing, material to be processed may be covered with a support layer of a material which is selected in view of desired mechanical and thermal properties, and which is not amenable to patterning by radiation. A method is described which provides for patterning of such layer by heated mechanical means such as a heated stylus or roller.

摘要： A method for removing an epitaxial film from a single crystal substrate upon which it is grown and adhering the films to second substrate and the resultant structure. The removing method comprises (a) providing a thin release layer (.ltoreq.100 nm) between the film to be grown and the single crystal substrate; (b) growing the epitaxial film; (c) applying a polymeric support layer which is under tension over the film; and (d) selectively etching the release layer, the tension in the support layer causing the edges of the film to curve upwardly as the release layer is etched away. The adhering method uses either adhesives or relies solely on Van der Waals bonding between the epitaxial film and the second substrate.

摘要： The spiral sheet antenna allows a small efficient antenna structure that is much smaller than the electromagnetic wavelength. It achieves the small size by introducing a high effective dielectric constant through geometry rather than through a special high dielectric constant material. It typically includes a rectangular cylinder-like shape, with a seam. The edges of the seam can overlap to make a high capacitance, or they can make a high capacitance by simply having the edges of the seam very close to each other. The high capacitance serves the same role as a high dielectric constant material in a conventional compact antenna.

摘要： A two dimensional periodic pattern of capacitive and inductive elements defined in the surface of a metal sheet are provided by a plurality of conductive patches each connected to a conductive back plane sheet between which an insulating dielectric is disposed. The elements acts to suppress surface currents in the surface defined by them. In particular, the array forms a ground plane mesh for use in combination with an antenna. The performance of a ground plane mesh is characterized by a frequency band within which no substantial surface currents are able to propagate along the ground plane mesh. Use of such a ground plane in aircraft or other metallic vehicles thereby prevents radiation from the antenna from propagating along the metallic skin of the aircraft or vehicle. This eliminates surface currents between the antenna and the ground plane thereby reducing power loss and unwanted coupling between neighboring antennae. The surface also reflects electromagnetic waves without the phase shift that occurs on a normal metal surface. This allows antennas to be constructed that were previously impractical.
