Abstract: A system, method, device, and apparatus provide a dielectric waveguide splitter/bi-directional link. A dielectric substrate fabricated into a first Y-junction waveguide with a first port splitting into a first branch leading to a second port and a second branch leading to a third port. An angle between the first branch and the second branch is below ninety degrees (90°). The dielectric waveguide splitter enables millimeter-wave (mmWave) transmission between the first port and the second port while reducing feedback of the mmWave between the second and third port. Two Y-junction waveguides may be fabricated back-to-back to provide simultaneous bidirectional mmWave transmission at a single frequency.

Abstract: Low-loss terahertz switches with nanometer resolution positioning and feedback are disclosed. In one embodiment, the switch uses a U-bend waveguide surrounded by an electromagnetic band gap and is implemented in a fully metal-machined fashion in combination with a piezo-electric motor and an optical linear encoder. In another embodiment, the switch comprises a MEMS device.

Abstract: A set of antenna geometries for use in integrated arrays at terahertz frequencies are described. Two fabrication techniques to construct such antennas are presented. The first technique uses an advanced laser micro-fabrication, allowing fabricating advanced 3D geometries. The second technique uses photolithographic processes, allowing the fabrication of arrays on a single wafer in parallel.

Abstract: A multi-pixel terahertz transceiver is constructed using a stack of semiconductor layers that communicate using vias defined within the semiconductor layers. By using a stack of semiconductor layers, the various electrical functions of each layer can be tested easily without having to assemble the entire transceiver. In addition, the design allows the production of a transceiver having pixels set 10 mm apart.

Abstract: A system for wirelessly communicating between a base station and a mobile device, including a reflector integrated with a mobile device, wherein the reflector reflects carrier radiation transmitted from a base station, to form a reflection of the carrier radiation, and input data from the mobile device modulates a reflection coefficient of the reflector, thereby modulating the reflection such that the reflection of the carrier radiation carries the input data to the base station.
