Abstract:
When using micro-resonant structures, it is possible to use the same source of charged particles to cause multiple resonant structures to emit electromagnetic radiation. This reduces the number of sources that are required for multi-element configurations, such as displays with plural rows (or columns) of pixels. In one such embodiment, at least one deflector is placed in between first and second resonant structures. After the beam passes by at least a portion of the first resonant structure, it is directed to a path such that it can be directed towards the second resonant structure. The amount of deflection needed to direct the beam toward the second resonant structure is based on the amount of deflection, if any, that the beam underwent as it passed by the first resonant structure. This process can be repeated in series as necessary to produce a set of resonant structures in series.
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 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. 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 charged particles therefore follow an oscillating trajectory. When the electric fields are selected to produce oscillating trajectories having the same (or nearly the same) as a multiple of the frequency of the emitted x-rays, the resulting photons can be made to constructively interfere with each other to produce a coherent x-ray source.
Abstract:
A display of wavelength elements can be produced from resonant structures that emit light (and other electromagnetic radiation having a dominant frequency higher than that of microwave) when exposed to a beam of charged particles, such as electrons from an electron beam. An exemplary display with three wavelengths per pixel utilizes three resonant structures per pixel. The spacings and lengths of the fingers of the resonant structures control the light emitted from the wavelength elements. Alternatively, multiple resonant structures per wavelength can be used as well.
Abstract:
We describe 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 with pulsed electroplating techniques using ultra-short pulses in a controlled and predictable manner.
Abstract:
We describe a new method for etching patterns in silver, copper, or gold, or other plate metal thin films. A pattern of a hard mask is placed onto the surface of the thin film, followed by a step of reactive ion etching using a plasma formed using a gas feed of some combination of some amounts of methane (CH4) and hydrogen (H2), and some or no amount of Argon (Ar). The areas of silver, copper or gold not covered by the hard mask are etched while the hard mask protects those areas that will form the raised portions of thin film in the final 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(s) 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 undeflected. 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:
We describe an ultra-small resonant structure that produces electromagnetic radiation (e.g., visible light) at selected frequencies that can also be used or formed in conjunction with passive optical structures. The resonant structure can be produced from any conducting material (e.g., metal such as silver or gold). The passive optical structures can be formed from glass, polymer, dielectrics, or any other material sufficiently transparent using conventional patterning, etching and deposition techniques. The passive optical structures can be formed directly on the ultra-small resonant structures, or alternatively on an intermediate structure, or the passive optical structures can be formed in combination with other passive optical structures. The size and dimension of the passive optical structures can be identical with underlying structures, they can merely extend outwardly beyond an exterior shape of the underlying structure, or the passive optical structures can span across a plurality of the underlying structures, including in each instance embodiments with and without the intermediate structures.
Abstract:
An electronic transmitter or receiver employing electromagnetic radiation as a coded signal carrier is described. In the transmitter, the electromagnetic radiation is emitted from ultra-small resonant structures when an electron beam passes proximate the structures. In the receiver, the electron beam passes near ultra-small resonant structures and is altered in path or velocity by the effect of the electromagnetic radiation on structures. The electron beam is accelerated within a series of spiral-shaped anodes to an appropriate current density without the use of a high power supply. Instead, a sequence of low power levels is supplied to the sequence of anodes in the electron beam path. The electron beam is thereby accelerated to a desired current density appropriate for the transmitter or receiver application without the need for a high-level power source.
Abstract:
An optical transmitter produces electromagnetic radiation (e.g., light) of at least one frequency (e.g., at a particular color frequency) by utilizing a resonant structure that is excited by the presence a beam of charged particles (e.g., a beam of electrons) where the electromagnetic radiation is transmitted along a communications medium (e.g., a fiber optic cable). In at least one embodiment, the frequency of the electromagnetic radiation is higher than that of the microwave spectrum.
