Abstract:
A charged particle beam including charged particles (e.g., electrons) is generated from a charged particle source (e.g., a cathode or scanning electron beam). As the beam is projected, it passes between plural alternating electric fields. In one embodiment, the electric fields alternate not only on the same side but across from each other as well. The attraction of the charged particles to their oppositely charged fields accelerates the charged particles, thereby increasing their velocities in the corresponding (positive or negative) direction. The velocity oscillation direction can be either perpendicular to the direction of motion of the beam or parallel to the direction of motion of the beam.
Abstract:
An electronic receiver for decoding data encoded into electromagnetic radiation (e.g., light) is described. The light is received at an ultra-small resonant structure. The resonant structure generates an electric field in response to the incident light and light received from a local oscillator. An electron beam passing near the resonant structure is altered on at least one characteristic as a result of the electric field. Data is encoded into the light by a characteristic that is seen in the electric field during resonance and therefore in the electron beam as it passes the electric field. Alterations in the electron beam are thus correlated to data values encoded into the light.
Abstract:
A process to produce ultra-small structures of between ones of nanometers to hundreds of micrometers in size, in which the structures are compact, nonporous and exhibit smooth vertical surfaces. Such processing is accomplished using a non-conductive or semi-conductive substrate on which a layer of a conductive material, such as a conductive polymer, is applied, and on which a second layer of a masking material, such as a pattern resist material, is applied. Following patterning of the second resist layer, and either the full or partial etching of the conductive polymer, or alternatively omitting the step of etching the conductive layer, electroplating techniques will be used to produce ultra-small structures on the substrate or alternatively directly on the conductive layer, after which either all of remaining portions of the conductive polymer layer and the resist layer will be removed, or only the resist layer will be removed, or alternatively neither will be removed.
Abstract:
We describe an ultra-small resonant structure that produces electromagnetic radiation (e.g., visible light) at selected frequencies. The resonant structure can be produced from any conducting material (e.g., metal such as silver or gold). In one example, a number of rows of posts are etched or plated on a substrate, with each row having a particular geometry associated with the posts and cavities between the posts. A charged particle beam is selectively directed close by one of the rows of posts, causing them to resonate and produce radiation (e.g., in the visible spectrum at a predominant frequency). Directing the charged particle beam at a different row yields radiation at a different predominant frequency.
Abstract:
We describe an ultra-small structure that produces visible light of varying frequency, from a single metallic layer. In one example, a row of metallic posts are etched or plated on a substrate according to a particular geometry. When a charged particle beam passed close by the row of posts, the posts and cavities between them cooperate to resonate and produce radiation in the visible spectrum (or even higher). A plurality of such rows of different geometries can be etched or plated from a single metal layer such that the charged particle beam will yield different visible light frequencies (i.e., different colors) using different ones of the rows.
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.

A device includes an integrated circuit (IC) and at least one ultra-small resonant structure and a detection mechanism are formed on said IC. At least the ultra- small resonant structure portion of the device is vacuum packaged. The ultra-small resonant structure includes a plasmon detector having a transmission line. 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.
Abstract:
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.
