Matthias Wuttig

RWTH Aachen University

Novel Optical Materials by Design: The Role of Chemical Bonding

Optical Materials with tunable properties enable a plethora of advanced photonic applications. To fully exploit the potential of this material class, design rules for the corresponding optical properties are desirable. Here, we identify stoichiometry trends in a wide range of chalcogenides and related materials. A quantum-chemical map explains these trends and provides a blueprint to design novel optical materials.

About the Speaker

Developing novel materials is the goal of Matthias Wuttig's work. In doing so, he relies on an unconventional approach, the development of 'treasure maps' to identify promising materials. This has enabled the identification of fundamental relationships between relevant material properties and the underlying chemical bonding mechanism. He is particularly interested in the design of materials for photonic applications, data storage and energy conversion. After his PhD he spent time in Marseille, Tsukuba, Berkeley, Murray Hill (Bell Labs) and the Research center Jülich, before he moved to RWTH Aachen in 1997. There he was speaker of the Strategy Council, Dean of the Faculty of Mathematics, Informatics and Natural Sciences and has been the speaker of the Collaborative Research Center Nanoswitches since 2011. He has received various scientific awards and funding for his work, such as an ERC Advanced Grant.

Quantum Communications and Computing Systems

This Joint Symposium is the result of the cooperation between the Networks, SPPCom, and NP topical meetings.

Secure quantum networks and quantum computers are among the hottest R&D topics in the information processing and communications field. Emerging quantum technologies such as the advent of 127-qubit processors, progress in quantum cryptography and quantum key distribution, as well as network connectivity between quantum computers and sensors over quantum networks, have opened up novel application areas. Error correction and fault tolerance, however, still remain very challenging, and do not yet come close to the capabilities of classical systems.

While quantum technology will not eliminate the conventional way of computing and information processing/communication, some problems and applications ask for the specific advantages offered uniquely by quantum technology: The handling of problems beyond-classical computational complexity and speed, as well as quantum security. It is also in this context that optical technologies, and in particular integrated photonics, will play a significant role.

This symposium aims at reporting and discussing trends in practical applications of photonic quantum technologies and fosters the interaction of classical and quantum photonic researchers.

SDM Challenges and Perspectives

The sustained traffic growth in the different optical networks segments makes activating additional spatial dimensions essential. Space-division multiplexing (SDM) solutions include multicore fibers, multimode fibers, or cables with a high number of single-mode fibers. SDM transmission can be carried out without channel coupling (e.g., over single-mode fiber bundles or uncoupled multicore fibers) or with channel coupling (e.g., over few-mode fibers or coupled multicore fibers).  While uncoupled SDM enables easier integration with the existing transmission, amplification, and detection technologies, coupled transmission can offer component integration gains and cost savings. Uncoupled transmission seems to gain momentum in specific network segments, such as submarine space. On the other hand, the transmission of coupled signals remains a research topic raising interest from new players. This special session will discuss the challenges and perspectives of introducing SDM in optical systems and networks, bringing together experts from industry and academia working in the field.

SDM and Multi-Band Networks: Competing or Complementary Approaches?

In recent years, both new optical fiber transmission windows (O/E/S-band) and new optical fibers carrying orthogonal data channels have been widely explored as technologies to meet the ever-increasing demand for new data services. Broadly termed as "multi-band" or "space-division multiplexing (SDM)" these approaches both cover a range of technologies targeted in a variety of network contexts. In some areas multi-band and SDM technologies may complement each other or exist as part of the same network evolution strategy, whereas in many areas operators may face a direct choice between competing technologies.

In this workshop, we explore the intersection between multi-band and SDM technologies. With a range of expert speakers from industry and academia we aim to identify in which network contexts these approaches lead to competing technologies, if either has clear advantages, and where synergies between them may lie. In addition to exploring the latest research results and trends of these technologies, the workshop also invites operators to give their view on their commercial potential.

Symposium on Machine Learning and Autonomous Design for Photonic Devices

Integrated photonic devices provide a versatile platform for different applications, such as telecommunications, quantum information processing, and biosensing. The design of photonic components promises to improve the efficiency of photonic devices. However, designing integrated photonic components and circuits remains a major challenge due to their complex structures with large combinations of features. Machine learning techniques are capable of modeling and optimizing the response of photonic components much faster than the traditional design methodologies. The novel machine learning design frameworks for photonic devices, such as, artificial neural networks, deep neural networks, and deep generative networks, have generated promising results in designing and modeling integrated photonic devices in recent years.

This symposium will introduce machine learning and autonomous design for photonic devices. It will provide a broad range of insights, including but not limited to artificial neural networks, deep neural networks, deep generative networks, and autonomous design.

Symposium on Optical Fiber and Grating Based Biomedical Sensors

This Symposium will bring together photonic device designers, physicists and (bio)chemists to review the most advanced optical fiber devices (optical fibers, fiber gratings and other waveguide technologies) able to detect (bio)chemical analytes and/or perform biomedical applications with high sensitivity, selectivity, and robustness, while lowering the limit of detection to levels required in practical applications. 

Invited and Contributed talks will focus on tailoring light coupling mechanisms between engineered optical waveguides and their functional surface (if any) in response to external perturbations or surrounding medium changes. Specifically, the aim will be to understand how to optimize the transducing mechanisms to (1) encode the presence of a given analyte in a measurable change in the optical device properties or (2) achieve a specific functionality including tweezing or micro-surgery among others, ensuring in all cases reliability, reproducibility and robustness for in vitro or even in situ applications. 

Of particular importance are issues regarding the refractive index modulation, optical properties of the devices, scattering, porosity and thickness of the functional layers and how these parameters can be optimized to enhance the overall performances. Functionalization strategies for bare, metal-coated, oxide-coated or graphene-coated glass and polymer surfaces for Surface Plasmon Resonance (SPR) based sensors or nanoparticle-assisted devices will also be reviewed and discussed.

Symposium on Recent Advances in Ultrafast Laser Waveguide Writing in Transparent Materials

Organized by BGPP: Roberto Osellame, CNR - Institute for Photonics and Nanotechnologies, Italy; Réal Vallée, COPL, Laval University, Canada

Since the 1996 seminal paper [1], the field of ultrafast laser waveguide writing in transparent materials has grown significantly. Once a lab peculiarity, the method is now used by many start-up companies for real-world applications and has, in many cases, proven competitive to existing and well-entrenched photolithographic approaches. Nevertheless, ultrafast laser waveguide writing remains an intriguing topic for research. On the one hand, it is often the only technique that can produce optical waveguides in many important materials opening up device miniaturisation across different fields. On the other hand, improving our fundamental understanding of the modification mechanism involved with irradiating materials can still provide new and significant improvements to waveguide properties.

This special symposium forms part of the 2022 BGPP Topical Meeting. Submissions reporting on novel results across applications utilizing waveguide writing, from optical communications to quantum optics and astrophotonics, are welcomed. In addition, papers are being solicited to present new insights on the refractive index modification mechanisms and in the demonstration of laser waveguide writing within new materials that have the potential to open additional new applications.

The topics of solicited submissions include but are not limited to waveguide writing for:

• Optical communication devices

Panel Discussion: Energy Crisis and Climate Catastrophe – The Role of Solar Energy

Tuesday, 26 July 18:45 – 19:30

In addition to the growing climate crisis, the past few months have made it painfully clear that European energy independence also has important strategic implications for the future. Numerous studies have shown that photovoltaic technology can supply a significant fraction of the carbon-free electricity that will be needed in the future based on a solar resource that is freely available to most of the Continent. In this panel discussion, we bring together representatives from politics, academia, and industry to discuss the potential of PV to help decarbonize Europe’s energy system and what near-term actions must be taken to realize this goal.

Organizer

• Klaus Jaeger, Helmholtz-Zentrum Berlin, Germany

Speakers

• Arthur Daemers, Solar Power Europe, Belgium
• Ivan Gordon, IMEC, Belgium
• Jimmy Melskens, HyET Solar BV, Netherlands

BGPP Industry Session

Wednesday, 27 July 14:30 – 16:00

BGPP 2022 continues the long-standing tradition of addressing fundamental and technical issues of immediate and long-term application of fiber Bragg gratings and other devices fabricated by laser-matter-interaction. While fundamental aspects are covered by invited and contributed proceeding papers, the technical aspect is addressed in the Industry Session.

Speakers from FiSens, Photonova, Inc. and FBGS have been invited to make a 10 min presentation to showcase their advanced products, to explain the underlying technology and working principle. Company professionals that are also presenting scientific work during the conference have been favored. Therefore, the scientists in the auditorium working in closely related areas may get easily into contact with the company professionals for various reasons. Scientist may see how applied research translates into new products and applications. Junior scientists may be stimulated to create tomorrow a start-up in the field or join a company. In this way BGPP encourages greater interaction between the industry professionals and scientist.

Speakers include:
Tristan Kremp, OFS Fitel LLC, USA
Guillaume Laffont, CEA Saclay, France
Sébastien Loranger, PhotoNova, Inc., Canada
