  • Geometry in learning theory 파일영상 +강의담기 학문/산업 분야별 강좌 ▶ 지능형 로봇 ▶ 세미나 및 튜토리얼

     

     Geometry is a useful tool to analyze algorithms. Although the information geometry has also produced good results by combining with statistics.
     In this talk, I introduce some ideas for learning theory based on the elementary geometry applied to analyses of adaptive filters and support vector machines.

  • CMOS integrated circuits and system for affordable terahertz electronics 영상 +강의담기 학문/산업 분야별 강좌 ▶ 반도체 ▶ 세미나 및 튜토리얼

     

    Sub-terahertz and terahertz waves, electromagnetic waves within the frequency range from 100GHz to 10THz, enable unprecedented capabilities thanks to their unique characteristics, such as short wavelength, wide bandwidth and spectral specificity. Key applications include high-resolution imaging, high-speed data communication and gas analysis with absolute specificity through rotational spectroscopy. However, the high cost of the terahertz instrumentation has been limiting its proliferation. If developed, compact and low-cost terahertz electronic systems will accelerate the adoption of terahertz technologies in everyday life. Si-based terahertz electronics can be one of the key enabler of such systems.

    In this seminar, Si CMOS integrated circuits for terahertz applications will be introduced. Following a brief discussion on the tradeoffs and design approaches for CMOS terahertz circuit design, details of example circuits will be presented. The example circuits include 1) a 410-GHz short-range imaging receiver 2) a 240-GHz wideband receiver for rotational spectroscopy 3) a 300-GHz QPSK transmitter for 30-Gbps dielectric waveguide communications.

  • MEMS-Based Bio Devices, Liquid Metal Electronics and Nanophotonics 영상 +강의담기 학문/산업 분야별 강좌 ▶ 반도체 ▶ 세미나 및 튜토리얼

     

    MEMS technologies have enabled many innovative applications across various disciplines. In this talk, recent developments of MEMS-enabled implantable biomedical micro devices, liquid metal microfluidics and nanophotonics developed at UT Dallas will be presented. Examples of the implantable micro devices include a fully-integrated inductively-coupled battery-less wireless pressure sensor for intraocular pressure sensing application, a fully-integrated inductively-coupled wireless micro neurostimulator forchronic pain management, and a micro cell container for β-cell transplantation for diabetes treatment. For the liquid metal microfluidics, fundamental studies on the microfluidic platforms for liquid metal manipulation and its enormous potential along with wide range of applications will be discussed. Nanophotonics is an emerging field of study which deals with interaction of light with nano scale matters. While there have been many fascinating demonstrations in nanophotonics, adding on-demand tunability to the nanophotonics would greatly expand existing application areas and potentially enable unforeseen new applications. Among many exciting “tunable” nanophotonics, this talk gives a review about recent developments of tunable nano photonic devices using MEMS.

  • Vertical silicon nanowires for image sensor applications 영상 +강의담기 학문/산업 분야별 강좌 ▶ 반도체 ▶ 세미나 및 튜토리얼

     

    Conventional image sensors achieve color imaging using absorptive organic dye filters. These face considerable challenges however in the trend toward ever higher pixel densities and advanced imaging such as multispectral imaging and polarization-resolved imaging. In this talk, we will present a new paradigm for color imaging based on all-silicon nanowire devices without any color filters. We fabricate pixels consisting of vertical silicon nanowires with integrated photodetectors, demonstrate that t heir spectral sensitivities are governed by nanowire radius, and perform color imaging. We also demonstrate polarization-resolving photodetectors consisting of silicon nanowires with elliptical cross sections. Our approach is conceptually different from filter-based methods, as absorbed light is converted to photocurrent, ultimately presenting the opportunity for very high photon efficiency. This work was performed at Harvard University under the supervision of Prof. Kenneth B. Crozier.

  • High performance InAs quantum dot lasers epitaxially grown on on-axis (001) Si for silicon photonics 영상 +강의담기 학문/산업 분야별 강좌 ▶ 반도체 ▶ 세미나 및 튜토리얼



    Quantum dot
    lasers epitaxially grown on Si are promising for an efficient light source for
    silicon photonics. In the talk, I will present record-high performance and
    excellent reliability of 1.3 μm quantum dot lasers on Si enabled by a low
    threading dislocation density GaAs buffer layer. Continuous-wave threshold
    currents as low as 4.8 mA and output powers of 185 mw have been achieved from
    narrow ridge-waveguide lasers at 20 °C. P-modulation doped lasers operated up
    to 107 °C. 1800-hour reliability tests at 35 °C showed an extrapolated
    mean-time-to-failure of more than a million hours. Micro-ring QD lasers on Si
    were also fabricated and showed an ultralow threshold current of 0.5 mA. I will
    also present a preliminary result on monolithically integrated III/V laser,
    waveguide, and photodetectors on Si. This represents a significant stride
    toward efficient, scalable, and reliable III-V lasers on on-axis Si substrates for
    photonic integrate circuits that are fully compatible with CMOS foundries.
