Single-chip sub-THz solutions for biomedical, security, communication, and large-scale array applications

Abstract: Efficient, controlled, and low-cost conversion to THz power remains a big challenge. This has lead to the so-called THz gap, both in terms of available power and in terms of explored applications. These frequencies (0.1 THz-10 THz) have wide and important applications in physics, medicine, technology, biology, and security. Some specific areas include: medical imaging and screening, extremely high-throughput short-range communication, control and manipulation of molecular dynamics and configurations, spectroscopy, and large-scale security screening. However, today’s systems are expensive, costing between $100K−$1M, and do not provide the performance metrics required for many of the target areas. Furthermore, these systems are not portable and require high power for operation. Research into efficient generation, control, detection, guided-transmission, radiation and filtering of THz signals can results in significant steps towards experiments in this area. This presentation will provide an overview of some of our efforts in the design of extremely wideband sub-THz fully integrated systems in silicon technology. Generation, manipulation, and detection of ultra-short mm-Wave pulses will be examined. A fully- integrated 94GHz single-chip pulse radar with time-array functionality will be presented and discussed. Novel approaches for extreme wideband amplification plus narrow and accurately controllable pulse generation, the key challenges in attaining image quality for sub-THz imaging, are addressed. The transmitter uses a smart antenna network, the Antentronic structure, to obtain improved transmit bandwidth. At the end, future applications of these technologies will be discussed.
