Ultrafast electrical signals: Transmission of broadband guiding structures and transport in the resonant tunneling diode
This study documents the experimental study of the transmission of picosecond electrical signals as they propagate along planar guiding structures and as they are switched by double-barrier heterostructure diodes. Applying advances in the field of ultrafast optics to revolutionary techniques in the generation and measurement of short electrical transients, a large contribution has been made to the growing field of ultrafast electronics. The progress of this discipline, which is essential to the future progress of the communications and computer fields, has to be furthered by the investigation of sources of high-speed digital signals and the means of transmitting these signals. An algorithm has been developed and used to model the propagation of picosecond and subpicosecond electrical signals on normal and superconducting planar transmission lines. The effects of the modal dispersion of planar lines, the complex surface conductivity of superconductors, and the dipolar relaxation of substrates are demonstrated. Additionally, an investigation into the switching speed of the double-barrier quantum-well resonant-tunneling diode produced the first observation of picosecond bistable operation in this device.
