SUMMARY:ESE Spring Seminar - "Building Photonic Systems for Extreme-Scale Computing\, Particle Accelerations\, and Beyond"
DESCRIPTION:A photonic-electronic system can potentially process enormous amounts of data that no stand-alone electronics have been capable of. Furthermore\, a chip-scale optical atomic clock can be so precise that it only loses the equivalent of one second every million years. In the foreseeable future\, highly integrated photonics can usher disruptive advances in communications\, deep learning\, and atomic-photonic integration. \nTo realize this vision\, my research has built multi-levels of the photonic system stacks from discrete nanophotonic devices\, all the way to creating advanced system-level demonstrations. In this talk\, I will introduce recent experiments where we demonstrate natively error-free terabit/s data transmission using integrated frequency combs and multi-dimensional silicon photonics circuits [1]. The frequency comb device transduces a narrow linewidth laser into a series of replicas over hundreds of frequency modes [2]. We employed photonic inverse design for wavelength and spatial multiplexing to enable bandwidth density on silicon photonic circuits to be three orders of magnitude higher than that of optical fibers. \nI will conclude my talk with applications and prospects for large-scale photonic systems that can manipulate atoms\, ions\, and free electrons\, along with my preliminary studies on UV-visible nonlinear optics and laser particle accelerations on a chip [3]. \n[1] K.Yang\, …\, J.Vuckovic\, arXiv: 2103.14139 (2021). \n[2] K.Yang\, …\, K.Vahala\, Nature Photonics 12\, 297 – 302 (2018); M.Guidry*\, D.Lukin*\, K.Yang*\, …\, J.Vuckovic\, Nature Photonics 16\, 52 – 58 (2022). \n[3] D.Oh*\, K.Yang*\, …\, K.Vahala\, Nature Communications 8\, 13922 (2017); N.Sapra\, K.Yang\, …\, J.Vuckovic\, Science 367\, 79 – 83 (2020).
