摘要: Display devices are described in which certain structural features prevent cross-talk effects between individual display elements. This ensures sharp delineation between individual display elements which promotes high contrast and sharp displays. These structural features are particularly advantageous for multiplexed display systems so as to simplify circuit arrangements and ensure sharp, high-contrast displays.

摘要: A solid state electrical switch is described which exhibits high off/on resistance ratios and low insertion loss. An additional advantage is that removal of the switching energy does not alter the status (off or on) of the switch. The active solid state material in the switch is an electrochromic material (e.g., tungsten trioxide) which undergoes a transformation from insulator to metallic conductor on injection of certain ions.

摘要: An up converting method and apparatus includes a crystalline structure responsive to light emitted from pump light for producing visible and/or ultraviolet light therefrom which is of a shorter wavelength than the pump light. This crystalline structure comprises a composition containing active ions of trivalent rare earth elements and a host material of either anhydrous rare earth halides or rare earth oxysulfides. This crystalline structure is represented by the atomic formula M.sub.(1-x) R.sub.x Z.sub.3 or M.sub.2(1-x) R.sub.2x O.sub.2 S where M comprises at least one rare earth element selected from the group comprising cerium, gadolinium, yttrium, lanthanum, and mixtures thereof, R is a dopant selected from the group comprising neodymium, thulium, erbium, holmium, samarium, and mixtures thereof, x is a value in the range from 0.005 to 1.0, and Z is a halogen selected from the group comprising chlorine, bromine, and iodine. When optically pumped, the crystalline structure produces visible and/or ultraviolet light by either a direct or indirect two step up conversion process. An electronic printing apparatus can also use the up converting crystalline structures to expose photosensitive media in the manner of this invention.

摘要: Epitaxial layers of semi-insulating InP grown by MOCVD on conducting InP wafers make excellent substrates for III-V semiconductor devices. Particularly appealing is the low defect density obtained because of the conducting InP wafers and excellent insulating characteristics of the semi-insulating InP layer. The invention is a procedure for doping the insulating layer by ion implantation. Such a procedure is unusually advantageous for fabricating a variety of devices including MISFETs, MESFETs and JFETs.

摘要: A fabrication technique is described for making various devices in which a type of glass is used as a surface protection layer. The glass layers are put down by particle bombardment (generally sputtering) of a borosilicate glass target. Devices with such surface layers are also described. Such glass layers are highly advantageous as encapsulating material, diffusion barrier layers, etc., particularly for optical type devices and certain semiconductor devices. Particularly important is the preparation procedure for the glass target used in the bombardment process. The glass layers are moisture stable, act as excellent barriers against diffusion, and are usable up to quite high temperatures without cracking or peeling. The glass layers also provide long-term protection against atmosphere components including water vapor, oxygen, atmosphere pollution contaminants, etc.

摘要: A diode-pumped monolithic laser is fabricated from a self-doubling host material co-doped with two ionic species, where one ionic dopant converts pump radiation to continuous radiation at a fundamental frequency and the other dopant acts as a saturable absorber to Q-switch the fundamental radiation which is then frequency doubled to produce pulsed high-intensity green light, the green light being either outputted or further frequency-doubled, into pulsed coherent UV radiation, by means of a non-linear crystal.

摘要: Electrically activated components such as switches, modulators, attenuators, and mode selectors are disclosed which can be used in networks of waveguides in optical communications systems. Disclosed components comprise an electrochromic medium in combination with a suitable ion source and means for producing a variable electric field across the medium. A change of color in the medium in response to variation of the electric field strength is instrumental in influencing direction and intensity of light propagating in a network.
