<Abstract>

Nanotechnology is reshaping the frontiers of electronics, photonics, optoelectronics, energy, robotics, healthcare and biomedical engineering across a variety of disciplines. This talk will highlight recent advances that harness emerging nanomaterials and nanodevices to enable the future-generation sensing, communication, computation, energy harvesting, and quantum technologies. This first part of this talk will give an overview of recent progress on nanomaterial-enabled sensors, actuators, antennas, integrated circuits and systems, as well as practical applications in internet-of-things (IoTs), smart cities, wearable bioelectronics, electronic skins, telehealth, and 6G smart electromagnetic environments. The second part of this talk will discuss how synthetic nanostructures and nanofabricated metamaterials can be exploited to manipulate light beyond the sub-diffraction limit and significantly enhance nonlinear and quantum optical effects, paving the way toward the next-generation technologies in sensing, imaging, energy harvesting, optical modulation/multiplexing, intra/inter-chip communication, and quantum information, with unparalleled performance. The talk will conclude with a brief outlook on the future directions in nanophotonics and nano-optics, as well as their challenges in terms of cost-effective and scalable manufacturing.
