ABSTRACT: Being able to harness, synthesize, manipulate electromagnetic waves and transduce to and extract information from them forms the foundation of nearly all communication, sensing and imaging technologies that have transformed our lives and continue to do so. In the next few decades, this access is expected to expand orders of magnitude than ever before stretching from RF-to-THz-to-optical frequencies (GHz-PHz), creating a new generation of ubiquitous connected sensory technologies that not only allows us to interact with and monitor the physical world, but also learn, make intelligent decisions and perform autonomous actuation functions. Enabling these technologies that are extremely diverse across applications, spectrum and are multi-modal, reconfigurable and adaptable requires a new approach to synthesis and detection of the electromagnetic fields for information extraction and transduction.
In this talk, I will highlight some of our approaches to exploit electromagnetic interactions at sub-wavelength scales across these wide dimensional wavelengths (10 mm-500 nm) spanning across mm-Wave, THz and visible range frequencies in ICs, to enable new architectures and functionalities. In particular, will focus on three frequency/wavelength ranges to 1) (30-100 GHz) Frequency and EM-reconfigurable transceiver architectures for generalized scalable MIMO arrays 2) (100-1000 GHz) Universal chip-scale Active THz surfaces 3) (500-1000 nm) External optics-free fully integrated nano-optical systems in silicon (<10mm3 in volume) with multi-functional nano-plasmonic structures and ~100fM sensitivity. The latter can enable a new class of ultra-miniaturized massively multiplexed optical sensors for in-vitro and in-vivo sensing, diagnostics and personalized health. Harnessing such a spectral expanse in one integrated platform with techniques combining circuits, electromagnetics, optics and signal processing can lead to new capabilities and open untapped opportunities across a wide range of applications in communication, sensing and imaging.
