J Leuthold - "The Path towards 100 Gbit/s Wireless Communications"

Convener: Günter Steinmeyer

100 Gbit/s wireless communications is emerging as a solution to overcome the access network bottleneck. Yet, capacities above 100 Gbit/s require new technologies and photonic-electronic devices that can handle sub-THz carrier frequencies that allow for fast beam steering of pencil beams and that can process novel modulation formats. This tutorial session will review recent progress in the field and highlight the impact of novel technologies such as plasmonics to overcome the technological challenges on the path to Tbit/s wireless communications.

Commission D - "Microwave Photonics"

Conveners: Stavros Iezekiel, Jianping Yao

Microwave photonics (MWP) is an interdisciplinary field which as the name implies involves elements of both microwave engineering and photonics, typically for the generation, transmission and signal processing of microwave signals in the optical domain. The large time-bandwidth product and relatively low propagation losses of photonics have been a key motivation in the development of many MWP systems, allowing functionalities that would either be complex or not feasible with standard microwave components and techniques. This session will focus on some of the emerging applications and technologies in microwave photonics, such as 5G and integrated photonics.

Commission D - "Modeling of Electronic, Photonic and Plasmonic Devices"

Conveners: Ayhan Demircan, Jeremy Gulley

Advances in electro-photonic and plasmonic devices are critical for the further development of applications in computing, communications, and defense related technologies. Modern experiments with novel electro-photonic materials frequently require simulations to interpret the significance of physical processes. This is particularly important in several cases. One is the case of device interactions with strong external fields, where nonlinear effects play a decisive role in the material response. Another is the case of ultrafast processes, which require fully time-resolved modeling of the material evolution on the femtosecond or attosecond time scale. Still a another case is micro- and nano-electronics, where the quantum mechanical effects in the device largely determine its behavior. This session should attract papers advancing the fundamental understanding of electronic, photonics and plasmonic devices through theory and simulations. Specific topics of interest include strong field interactions with micro- and nano-electronics, electronic thermalization, nonlinear optics and photonics, propagation, and ultrafast processes in semiconductors and dielectrics.

Commission D - "Open Session: Recent Advances in Electronics and Photonics"

Conveners: Günter Steinmeyer, Apostolos Georgiadis

Electronics and photonics are ultimately different facets of Maxwell's equations. Optical radiation exhibits carrier frequencies in the range of several hundred terahertz whereas current microwave generation schemes are limited to a few hundred gigahertz at best. In between these two regions, there is a range of about three orders of magnitude where neither optical nor electronic synthesis or detection schemes appear easily applicable. This session features recent advancement in the field of electronics or photonics with particular emphasis on novel schemes to close the gap and to connect electronics with photonics. Contributions include photonic schemes for the implementation of electronic functionalities, electronic schemes that overcome frontiers, photonic signal processing schemes, optoelectronic and electro-optic applications. A particular focus is on electronics and photonics devices, circuits and systems for the purpose of implementing either previously unattainable functionalities or for improving the performance of current electronic-only or photonic-only technologies.

Commissions DA - "Optical Methods for Microwave Metrology"

Conveners: Mark Bieler, Yang Chuntao

The operating frequency and bandwidth of microwave devices is steadily increasing. Especially the development of novel communication technologies, sensors, and transducers imposes the need for exact and reliable measurements in this frequency range. This is mainly because devices cannot be improved if their functionality cannot be accurately characterized. Optical methods are well suited for characterization since (i) they offer an unprecedented bandwidth that is not accessible with purely electrical devices, (ii) allow for quasi-non-invasive measurements due to contactless probing, and (iii) enable straightforward traceability of the time and frequency axes to the unit of time. This session addresses such optical techniques, which can be employed for the measurement of electric, magnetic, and thermal signals and form the basis for microwave metrology.

Commissions DJ - "Special Session on Gravitational Wave Detection"

Conveners: Roman Schnabel, Lisa Borsotti, Willem Baan

The first observation of gravitational waves on September 14, 2015, by the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) heralded the field of gravitational-wave astronomy. It is expected that this field will provide information about the universe that was previously not accessible at all. Although gravitational-wave observatories are already extremely sensitive measurement devices, there are many ideas for further enhancements to increase the event rate by several orders of magnitude and to target specific sources of gravitational waves. A particular goal is reaching a sensitivity that will allow us to listen to the gravitational-wave background originating from the Big Bang.

Commissions JD - "AstroPhotonics"

Conveners: Martin Roth, Peter Maat, Stefan Minardi

Optical fibers and integrated optical devices are increasingly being used as key technologies to improve the performance of radio- and optical- astronomical interferometers and, in general, any optical astronomical instrument. To highlight the rapid development and growing importance of this specific area of applied photonics, the term AstroPhotonics has been recently devised. Beam forming devices, integrated optics delay lines, and clock distribution based on optical fiber networks are now commonly used to enhance the precision of radio-interferometric measurements, while reducing the impact of environmental electromagnetic noise and infrastructure cost. Recent advances in optical comb technologies bear promise to replace atomic clocks by much more accurate optical clocks, which could be easily interfaced to optical fiber networks to time the radio-telescopes. In the domain of optical interferometry, integrated optics multi-telescope beam combiners for near-infrared light are currently delivering the highest precision visibility measurements and enable reliable image retrieval of astronomical targets ranging from stellar surfaces to proto-planetary disks. Extension of these technologies to the visible and mid-infrared bands is currently an active research area, along with feasibility studies and on-field tests of direct telescope connection by means of optical fiber links. The aim of this session (including both invited and contributed talks as well as posters) is to bring together the radio- and optical-AstroPhotonic communities by presenting recent advances and new application concepts based on photonic technologies for astronomical interferometry. Differences and similarities between the photonic technologies and their applications employed by the two communities will be highlighted, in order to promote a fruitful cross-contamination of ideas and interdisciplinary collaboration. Eligible topics include: integrated optics devices and components for stellar interferometry (e.g. beam forming devices, homodyne and/or heterodyne interferometric beam combiners, integrated phase and/or amplitude modulators), all-optical delay lines, frequency combs generation, optical clocks, optical fiber networks and their opto-electronic management, long-haul interferometric fiber links.
