Abstract: Semiconductor optical modulators are described that utilize bipolar junction transistor (BJT) structure within the optical modulator. The junctions within the BJT can be designed and biased to increase modulator efficiency and speed. An optical mode may be located in a selected region of the BJT structure to improve modulation efficiency. The BJT structure can be included in optical waveguides of interferometers and resonators to form optical modulators.

Abstract: Using the Meissner effect in superconductors, demonstrated here is the capability to create an arbitrarily high magnetic flux density (also sometimes referred to as “flux squeezing”). This technique has immediate applications for numerous technologies. For example, it allows the generation of very large magnetic fields (e.g., exceeding 1 Tesla) for nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), the generation of controlled magnetic fields for advanced superconducting quantum computing devices, and/or the like. The magnetic field concentration/increased flux density approaches can be applied to both static magnetic fields (i.e., direct current (DC) magnetic fields) and time-varying magnetic fields (i.e., alternating current (AC) magnetic fields) up to microwave frequencies.
Abstract: A back-gate carbon nanotube field effect transistor (CNFETs) provides: (1) reduced parasitic capacitance, which decreases the energy-delay product (EDP) thus improving the energy efficiency of digital systems (e.g., very-large-scale integrated circuits) and (2) scaling of transistors to smaller technology nodes (e.g., sub-3 nm nodes). An exemplary back-gate CNFET includes a channel. A source and a drain are disposed on a first side of the channel. A gate is disposed on a second side of the channel opposite to the first side. In this manner, the contacted gate pitch (CGP) of the back-gate CNFET may be scaled down without scaling the physical gate length (LG) or contact length (LC). The gate may also overlap with the source and/or the drain in this architecture. In one example, an exemplary CNFET was demonstrated to have a CGP less than 30 nm and 1.6× improvement to EDP compared to top-gate CNFETs.
