Invited speakers > Invited talks

Andreas Beling, University of Virginia, USA, High Power Integrated 100 GHz Photodetectors

The talk reviews recent results from waveguide photodetectors, integrated photodiode-antenna emitters, and flip-chip bonded photodiodes with bandwidths up to 120 GHz. Recent results from heterogeneous III-V photodiodes on silicon for analog applications will be discussed.

Daniel Blumenthal, University of California Santa Barbara (UCSB), USA,  Photonic integration beyond silicon

Microwave photonics demands on photonic circuits go beyond what can be delivered with silicon photonics alone. The potential for next generation integration platforms, including silicon nitride and tantalum pentoxide, to handle high power, deliver low phase noise, and realize photonic microwave functional circuits will be described.

Mona Jarrahi, University of California Los Angeles (UCLA), USA, Plasmonic enhanced THz devices

I will describe some of our recent work on developing plasmonics-enhanced terahertz optoelectronic devices to achieve record-high terahertz radiation powers, detection sensitivities, and signal-to-noise ratios in various imaging, spectrometry, and spectroscopy systems for medical diagnosis, space explorations, industrial quality control, and environmental sustainability applications.

Thomas Kuerner, University of Braunschweig, Germany, THz communication challenges and applications beyond 100 G

Apart from research in academia THz communications has also triggered projects heading to develop appropriate technological solutions to enable the set-up of hardware demonstrators. In parallel discussions and activities in standardization and regulation already took off. This talk will discuss all three aspects of future THz communication systems.

Lute Maleki, GM, USA, Advances in LiDAR

LiDAR is now recognized as an important enabling sensor for many applications in remote sensing, robotics, and autonomous vehicles.  In this talk recent advances in LiDAR will be discussed, and future directions identified.  Particular emphasis will be placed on LiDAR for self-driving vehicles.

Loïc Morvan, Thales Research & Technology, France, RF spectrum analyzer for ultra-wide instantaneous bandwidth

We present an ultra-wideband RF spectrum analyzer based on spectral hole burning in a rare-earth ion-doped crystal. It monitors and records spectrums of complex signals over an instantaneous bandwidth above 20 GHz, with a time resolution below 10 μs, and a 100% probability of intercept.

Scott Papp, National Institute of Standards and Technology (NIST), USA, Photonic-chip frequency combs for optical synthesis and metrology

Optical-frequency combs are versatile tools for measuring time, identifying chemicals, and generating quantum states.  A new direction is to produce frequency combs through intriguing nonlinear behaviors of light in Kerr microresonators. I will discuss experiments that probe Kerr soliton comb formation and demonstrate ultra-precision measurements.

Hiroyuki Otsuka, Kogakuin University, Tokyo, Japan, 5G trials toward 2020 and the application of RoF in mobile systems

This talk reviews recent 5G trial results by NTT DOCOMO, e.g., high data transmission in 300 km/h mobility conditions, technical collaborations with industry partners. This talk also introduces fiber-optic relaying with simultaneous transmission and reception on the same carrier frequency using RoF technology.

Sébastien Tanzilli, University Côte d’Azur, France, Quantum photonics at telecom wavelengths

Guided-wave optics is often employed for producing telecom photonic entanglement. I will show how this resource has been exploited as an enabling technology for implementing fundamental tests of entanglement, establishing a QKD protocol over 150 km, and for sensing fiber dispersion with unprecedented precision.
