Abstract: The present invention relates to a method and apparatus for the generation, manipulation and detection of plasmon, and/or solitons, both linear and non linear, in semi-conductor heterostructures. The apparatus includes a galium arsonide substrate, a two-dimensional electron gas well (2-DEG) (160) form thereon and a thin layer of Aluminum galium arsonide (AlGaAs) placed thereover. Launcher (130) and receiver lines (132, 134, 136) are formed on the AlGaAs layer. Each of the launcher (130) and receiver lines (132, 134, 136) includes coplanar waveguides which preferably consist of two to three metal lines. One line is interconnected with a photoconductive switch (120) and can be pulsed. The other line or lines are grounded. Pulsing the line forms an electric field which can be detected. Between the launcher and (130) and the receiver (140), the plasmon can be modulated by one or more additional gates line extending over the 2-DEG.

Abstract: A method and apparatus for stabilizing glow plasma discharges by suppressing the transition from glow-to-arc includes a perforated dielectric plate having an upper surface and a lower surface and a plurality of holes extending therethrough. The perforated dielectric plate is positioned over the cathode. Each of the holes acts as a separate active current limiting micro-channel that prevents the overall current density from increasing above the threshold for the glow-to-arc transition. This allows for a stable glow discharge to be maintained for a wide range of operating pressures (up to atmospheric pressures) and in a wide range of electric fields include DC and RF fields of varying strength.
