We describe the opportunities, and the research challenges, presented in the development of 100-300GHz wireless communications and imaging systems. In such links, short wavelengths permit massive spatial multiplexing both for network nodes and point-point links, permitting aggregate transmission capacities approaching 1Tb/s. 100-300GHz radar imaging systems can provide thousands of image pixels and sub-degree angular resolution from small apertures, supporting foul-weather driving and aviation. Challenges include the mm-wave IC designs, the physical design of the front-end modules, the complexity of the back-end digital beamformer required for spatial multiplexing, and, for imaging, the development of system architectures requiring far fewer RF channels than the number of image pixels. We will describe transistor development, IC design, and system design, and describe our efforts to develop 140GHz massive MIMO wireless hubs, and 210GHz and 280GHz MIMO backhaul links.

6G wireless systems are expected to offer ubiquitous connectivity in presently under-served areas, potentially provided by satellite- and space-based internet-of-things applications. In the search for enabling technologies to achieve these expectations, molecular communication is an important alternative to conventional electromagnetic-based wireless communication. In this talk, we give a brief introduction to molecular communication, and discuss how it may be used to communicate in "wave-denied" environments, where connectivity is desired, but wireless cannot be used. We also show that molecular communication can achieve surprisingly high information rates, theoretically unlimited and practically in the gigabit-per-second range, making it a compelling technology for 6G. We finish with a discussion of the current state of the field and propose some experimental next steps.

Abstract: Perfect inline squeezers are both spectrally pure and have identical input and output temporal modes, allowing one to squeeze an arbitrary input quantum state in the sole input mode on which the device acts, while the quantum states of any other modes are unaffected. We study theoretically how to obtain a perfect pulsed inline squeezer in twin-beam systems by considering three commonly used configurations: unpoled single pass, poled single pass, and poled double pass. By obtaining analytical relations between the input and output temporal modes from the Bloch-Messiah decomposition of the discretized Heisenberg-picture propagator, we find that a double pass structure produces a perfect pulsed inline squeezer when operated in a frequency degenerate, symmetric group-velocity matched type-II configuration.
