Abstract:
An antenna system includes a dielectric structure formed on a substrate; an antenna, partially within the dielectric structure, and supported by the dielectric structure; a reflective surface formed on the substrate. A shield blocks radiation from a portion of the antenna and from at least some of the dielectric structure. The shield is supported by the dielectric structure.
Abstract:
When using micro-resonant structures, a resonant structure may be turned on or off (e.g., when a display element is turned on or off in response to a changing image or when a , communications switch is turned on or off to send data different data bits). Rather than turning the charged particle beam on and off, the beam may be moved to a position that does not excite the resonant structure, thereby turning off the resonant structure without having to turn off the charged particle beam. In one such embodiment, at least one deflector is placed between a source of charged particles and the resonant structure^) to be excited. When the resonant structure is to be turned on (i.e., excited), the at least one deflector allows the beam to pass by undefÊected. When the resonant structure is to be turned off, the at least one deflector deflects the beam away from the resonant structure by an amount sufficient to prevent the resonant structure from becoming excited.
Abstract:
A multi-chip module includes a plurality of chips; and a wavelength multiplexed optical connector, wherein at least some of the chips are optically interconnected via the wavelength multiplexed connector. Some of the chips have one or more nano-resonant structures constructed and adapted to emit electromagnetic radiation (EMR) in response to excitation by a beam of charged particles; and at least one waveguide conduit constructed and adapted to capture the EMR emitted by the at least one nano-resonant structure. The at least one waveguide conduit of a particular chip optically connects said particular chip to said wavelength multiplexed optical connector.
Abstract:
In order to reduce the exposure of a detector surface 180 of a photo-multiplier 160 to stray charged particles, an off-axis structure is interposed between the resonant structure and the detector surface of the photo-multiplier. By providing the off-axis structure with at least one reflective surface, photons are reflected toward the detector surface of the photo-multiplier while at the same time absorbing stray charged particles. Stray particles may be absorbed by the reflective surface or by any other part of the off- axis structure. The off-axis structure may additionally be provided with an electrical bias and/or an absorbing coating for absorbing stray charged particles.
Abstract:
Micro-resonant structures (110) form a part of an optical interconnect system that allows various integrated circuits to communicate with each other without being connected by signal wires. Substrates (105) have mounted thereon integrated circuits which include at least one optical communications section (110). Each optical communications section includes at least one transmitter and/or at least one receiver. Such transmitters may include at least one resonant structure, and such receivers may include a receiver for receiving optical emissions from at least one resonant structure. Substrates may also include, mounted thereon, at least one optical directing element such as a mirror, a lens, or a prism. Optical communications sections may also be isolated from each other using filters.

The detector mechanism includes a generator mechanism constructed and adapted to generate a beam of charged particles along a path adjacent to the transmission line; and a detector microcircuit disposed along said path, at a location after said beam has gone past said line, wherein the generator mechanism and the detector microcircuit are disposed adjacent transmission line and wherein a beam of charged particles from the generator mechanism to the detector microcircuit electrically couples a plasmon wave traveling along the metal transmission line to the microcircuit. The detector mechanism may be electrically connected to the underlying IC.

A method and apparatus for modulating a beam of charged particles is described in which a beam of charged particles is produced by a particle source and a varying electric field is induced within an ultra-small resonant structure. The beam of charged particles is modulated by the interaction of the varying electric field with the beam of charged particles.

A device couples energy from an electromagnetic wave to charged particles in a beam. The device includes a micro-resonant structure and a cathode for providing electrons along a path. The micro-resonant structure, on receiving the electromagnetic wave, generates a varying field in a space including a portion of the path. Electrons are deflected or angularly modulated to a second path.
