摘要： An optical electronic integrated circuit (OEIC) having optical waveguides as device interconnects. An optical waveguide is formed by depositing, in an oxygen-free atmosphere, a film of semiconductor material on a semiconductor substrate at a temperature that substantially diminishes the porosity of the film and the diffusion of material from the substrate into the film. The semiconductor film, which has an index of refraction greater than that of the substrate, is etched to form the optical waveguide on the substrate. The substrate also supports a plurality of active optical devices between which the optical waveguide extends. The substrate is preferably formed from gallium-arsenide and the waveguide from germanium. The active devices may also include these materials as well as aluminum-gallium-arsenide.

摘要： A hetero-junction tunneling transistor having a first layer of p++ silicon germanium which forms a source for the transistor at one end. A second layer of n+ silicon material is deposited so that a portion of the second layer overlies the first layer and forms the drain for the transistor. An insulating layer and metallic gate for the transistor is deposited on top of the second layer so that the gate is aligned with the overlying portions of the first and second layers. The gate voltage controls the conduction between the source and the drain and the conduction between the first and second layers occurs by vertical tunneling between the layers.

摘要： The present invention is achieved by layering a dielectric slab between a ground plane and a two dimensional quasi quantum well heterostructure and by switching between an unbiased state and a negative potential which is established between the quantum well heterostructure and the ground plane. In the unbiased state, the device supports wave propagation in the dielectric with a phase velocity similar to that of a wave propagating in a parallel plate waveguide. Upon application of the bias voltage, that is establishing a negative potential difference between contacts based on either side of the quantum well heterostructure, the conductivity of the quantum well decreases. Therefore, as the carrier wave propagates the wave interacts with a boundary similar to that of a dielectric-air interface. This new boundary condition, in turn, produces a faster phase velocity. Hence, toggling the bias modulates the quantum well conductivity which changes the phase velocity of the carrier wave.
摘要翻译： 本发明通过在接地平面和二维准量子阱异质结构之间分层电介质板并通过在量子阱异质结构和接地平面之间建立的无偏态和负电位之间切换来实现。 在无偏置状态下，器件支持电介质中的波传播，其相位速度与在平行板波导中传播的波的相位速度相似。 在施加偏置电压时，即基于量子阱异质结构的任一侧建立触点之间的负电位差，量子阱的电导率降低。 因此，当载波传播时，波与与介电 - 空气界面相似的边界相互作用。 这种新的边界条件反过来产生更快的相速度。 因此，切换偏置调制量子阱导电率，其改变载波的相速度。
