  • 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.

  • 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.

  • High-speed III-nitride laser diodes for visible light communication 영상 +강의담기 학문/산업 분야별 강좌 ▶ 반도체 ▶ 세미나 및 튜토리얼

    III-nitride laser diodes (LDs) have been developed for many applications such as optical storage, medical, and solid-state lighting. However, the performance of LDs grown on conventional polar (0001) c-plane GaN has been hindered due to polarization-induced electric fields, leading to a reduction of wave-function overlap. Recent progress on semipolar and nonpolar planes has shown significant improvement in high-power performance of LEDs and LDs by reducing the polarization-induced electric field. Conventional III-nitride LEDs have typical bandwidth limits in the MHz range due to comparatively long carrier lifetime (on the order of ns) and significant RC parasitic effect. Even worse, for white lighting configuration, the response is significantly limited by slow relaxation lifetime (on the order of μs) of phosphor conversion. However, recent studies on LDs for light fidelity (LiFi) applications have demonstrated more than GHz bandwidth and Gbit/s data transmission rate with inherent advantage of short photon lifetime. As an alternative to LED technology, the use of laser diodes (LDs) as a transmitter presents a viable approach to overcome the limitations of modulation bandwidth as well as the lighting efficiency. Despite of these merits, only limited studies have been reported for LD-based VLC and LiFi demonstration without notable improvement in modulation capabilities. Since semipolar and nonpolar LDs are expected to have higher differential gain and lower threshold than c-plane LDs as mentioned above, they also have high potential for improvements in modulation bandwidth. Thus, nonpolar and semipolar LD is potential candidate for future LiFi applications requiring high-capacity for high-speed data transmission as well as high-efficiency for lighting.

  • Future Developments in Neurorobotic Technology 영상 +강의담기 학문/산업 분야별 강좌 ▶ 지능형 로봇 ▶ 세미나 및 튜토리얼

    This lecture gives an introduction to neurorobotics and highlights future developments in neurorobotic technology. Participants will learn about the huge diversity of neurorobotic research which ranges from early simple models of robot control which are based on only a few neurons to the state-of-the-art closed-loop integration of large-scale brain simulations with detailed models of physical bodies. Based on this overview, the lecture highlights the open challenges in neurorobotics research how they will be addressed in the future development of the Neurorobotics Platform of the Human Brain Project.

  • Artificial Intelligence and Brain Science 영상 +강의담기 학문/산업 분야별 강좌 ▶ 인공지능 ▶

    Human brain functions have long served as the targets of development of artificial intelligent systems. Findings in neuroscience have provided guidance at multiple levels in the designs of machine learning architectures and algorithms. Today’s neuroscience, in turn, necessitates applications of artificial intelligence and machine learning algorithms for making sense of huge datasets.

    In this talk, I review examples of co-evolution of AI and brain science and consider how they can help each other for further progress.
