20090252495 | METHOD AND APPARATUS FOR DEMULTIPLEXING OPTICAL SIGNALS IN A PASSIVE OPTICAL NETWORK - Methods and structures are disclosed demultiplexing optical signals transmitted over an optical fiber into a silicon substrate and to multiple detectors. The silicon substrate has two spaced-apart surfaces and a diffractive element disposed adjacent to one of the surfaces. Each of the optical signals corresponds to one of multiple wavelengths. The optical signals are directed into the silicon substrate along a path through the first surface to be incident on the diffractive element. The path is oriented generally normal with the first surface and/or with the diffractive element, which angularly separates the optical signals such that each of the wavelengths traverses through the substrate in a wavelength dependent direction to the first surface. Each optical signal is steered from the first surface towards the second surface to be incident on different optical elements that direct them generally normal to the first surface to be incident on one of the detectors. | 10-08-2009 |
20100065887 | FIELD EFFECT TRANSISTOR SOURCE OR DRAIN WITH A MULTI-FACET SURFACE - FET configurations in which two (or more) facets are exposed on a surface of a semiconductor channel, the facets being angled with respect to the direction of the channel, allow for conformal deposition of a convex or concave S/D. A convex tip of the S/D enhances electric fields at the interface, reducing the resistance between the S/D and the channel. In contrast, a S/D having a concave tip yields a dual-gate FET that emphasizes reduced short-channel effects rather than electric field enhancement. The use of self-limiting, selective wet etches to expose the facets facilitates process control, control of interface chemistry, and manufacturability. | 03-18-2010 |

20090058305 | COMPACT HIGH CURRENT RARE-EARTH EMITTER HOLLOW CATHODE FOR HALL EFFECT THRUSTERS - An apparatus and method for achieving an efficient central cathode in a Hall effect thruster is disclosed. A hollow insert disposed inside the end of a hollow conductive cathode comprises a rare-earth element and energized to emit electrons from an inner surface. The cathode employs an end opening having an area at least as large as the internal cross sectional area of the rare earth insert to enhance throughput from the cathode end. In addition, the cathode employs a high aspect ratio geometry based on the cathode length to width which mitigates heat transfer from the end. A gas flow through the cathode and insert may be impinged by the emitted electrons to yield a plasma. One or more optional auxiliary gas feeds may also be employed between the cathode and keeper wall and external to the keeper near the outlet. | 03-05-2009 |
