    摘要： An optical component is formed on a silicon on insulator (SOI) substrate and has an array waveguide that demultiplexes an input light signal into N channels and provides that light signal to a corresponding set of N waveguide structures formed on a surface of the SOI substrate. The N waveguide structures provide the N channels of light to N optical detectors. Each optical detector is bonded to a surface of a corresponding one of the waveguide structures. The N channels of light pass through the N waveguide structures and are coupled into the N optical detectors so that light from a corresponding channel of the array waveguide is coupled into a corresponding optical detector and converted into an electrical signal.

    摘要： Methods and apparati for spatially encoding and decoding spread spectrum communication signals using broad band light sources are disclosed. The encoding algorithms involve the use of orthogonal spatial wavelets, which are preferably discrete attenuation functions of light from different sources so that the discrete attenuation function is imposed upon the spectrum of the light source. The function may be used either merely for providing an encoded channel or by providing a second mask that may be, for example, the complement of the discrete attenuation function so that the light beam is discrete with the first attenuation function.

    摘要： Several methods have been found to make p-type gallium nitride. P-type gallium nitride has long been sought for electronic devices. N-type gallium nitride is readily available. Discovery of p-type gallium nitride and the methods for making it will enable its use in ultraviolet and blue light-emitting diodes and lasers. pGaN will further enable blue photocathode elements to be made. Molecular beam epitaxy on substrates held at the proper temperatures, assisted by a nitrogen beam of the proper energy produced several types of p-type GaN with hole concentrations of about 5.times.10.sup.11 /cm.sup.3 and hole mobilities of about 500 cm.sup.2 /V-sec, measured at 250.degree. K. P-type GaN can be formed of unintentionally-doped material or can be doped with magnesium by diffusion, ion implantation, or co-evaporation. When applicable, the nitrogen can be substituted with other group III elements such as Al.

    摘要： An attractant bait composition has been discovered for the control of many species of roaches. A similar group of baits were also found to be effective for the control of wasps, flies, termites, and mosquitoes. The composition includes a food base, attractants, sweeteners, carriers, dispersants, surfactants, fragrances, preservatives and a toxicant or toxicants. Important further considerations in the design of a bait material is the consistency of the bait, taste of the bait, speed of action of the toxicant, type of toxicant and odor as perceived by the various insects.
