    In femto-iCOMB, we develop the first integrated femtosecond laser-based frequency comb that can serve as the basis for a wide variety of optical and Radio-Frequency (RF) technologies ranging from high resolution environmental and health sensing to LIDAR and RADAR. Femto-iCOMB is based on the successful EIC-pathfinder project FEMTOCHIP, where we demonstrate an integrated high power femtosecond laser enabling extremely low jitter on chip scale. Here, we tam the free running comb from the integrated femtosecond laser with on-chip continuum generation, carrier-envelope and repetition rate locking to an optical reference to become a fully stabilized femtosecond laser frequency comb (FSLFC) with extremely high frequency stability. We use the femto-iCOMB to pursue photonic microwave oscillators for a variety of applications ranging from autonomous driving to ultra-low phase noise oscillators for advanced signal generators and RF-test and measurement equipment and demonstrate these devices in relevant industrial environments for each application. These prototype field tests will validate the TRL levels achieved for each application and together with surveys of potential customers will inform the business case to be made for each potential product line.

    Major challenges of the European and worldwide society such as the climate crisis, insufficient environmental protection, food and pharmaceutical shortages, and military aggressions require technologies that substitute fossil fuels with sustainable energy sources in basically all industries. Following the green deal of the EU commission, the European continent shall become the first climate-neutral continent by 2050. The chemical industry is a major contributor to CO2 emissions, as it accounts for about 30% of the industry’s total energy use worldwide. Even though so-called photochemistry promises to sustainably produce chemical compounds by (sun)light, corresponding reactors suffer from insufficient light management, even in modern micro flow reactors, which hinders their upscaling to applications in industry. This is exactly where the key to the technological and economic breakthrough lies, and this is where reaCtor comes into play. It will contribute to the ambitious goal of a sustainable chemistry by developing and validating a novel type of light-driven chemical reactor with enormous scale-up potential for industrial applications. It will be based on an interdisciplinary and innovative technological approach, combining optical fibres for smart light management, metallic nanoparticles as efficient energy transmitters, nano- and micro-fabrication for micro-fluidic functionalization as well as monolithic optical integration, and flow chemistry as an eco-friendly and safe chemical technology. For the first time, a demonstrator of the novel reactor architecture will be set-up and benchmarked with relevant photochemical reactions. Ultimately, the proposed fibre-based microfluidic reactors will enable implementation of new and efficient routes driven by light to prepare pharmaceuticals, agrochemicals, and materials on both lab and industrial scales.

    Over the last 20 years, femtosecond lasers have led to a host of novel scientific and industrial instrumentation enabling the direct measurement of optical frequencies and the realization of optical clocks, a Nobel Prize winning technology. Initially developed for fundamental science, the potential of femtosecond lasers for a wide range of cross-disciplinary applications has been demonstrated, including e.g. those in optical telecommunication, photonic analog-to-digital conversion, ultra-high precision signal sources for the upcoming quantum technologies and broadband optical spectroscopy in the environmental or bio-medical sciences and many more. Although, impressive cross-disciplinary demonstrations of the potential of femtosecond lasers are numerous, the technology has been hampered by its large size and high cost per system. The existing mode-locked semiconductor diode laser technology does not fulfil the needed performance specifications. The aim of the FEMTOCHIP project is to deliver a fully integrated chip-scale mode-locked laser with pulse energy, peak power and jitter specifications of a shoebox sized fiber laser system enabling a large fraction of the above-mentioned applications. Key challenges addressed are large cross-section, high gain, low background loss waveguide amplifiers, low loss passive waveguide technology and chirped waveguide gratings to accommodate high pulse peak power, to suppress Q-switching instabilities and to implement short pulse production by on-chip dispersion compensation and artificial saturable absorption. Therefore, the FEMTOCHIP consortium is composed of leaders in CMOS compatible ultra-low loss integrated SiN-photonics, rare-earth gain media development and deposition technology as well as ultrafast laser physics and technology for design, simulation and characterization to identify and address the key challenges in demonstrating a highly stable integrated femtosecond laser with table-top performance.

    The need for a next-generation computing platform becomes clear from IoT and 5G/6G and their high performance and low power requirements. Now, graphene and 2D materials (2DM) offer the unique ability to enable highly confined nonlinear interactions of light at low powers and at extremely low response times in the femtosecond range. However, it must be integrated with CMOS low-loss silicon nitride (SiN) platform that facilitates the possibility to create circuits for fast, low power, high bandwidth, general purpose computing and memory completely in the optical domain. As the most important challenge comes from the maturity of the graphene processes with standard CMOS environments, the main goal of GATEPOST is to fabricate and demonstrate a radically new graphene-based all-optical data processing platform, integrated and tested in a real CMOS pilot line. As a user case, we focus on a network security device for distributed denial of service (DDoS) detection and network packet inspection. Even though on average 170 cyber-attacks are performed per IoT device per day, there is still a huge lack of security due to the added power, latency, operating costs and bandwidth limitations involved. This is unacceptable, especially considering that the cybercrimes topped an estimated $318 billion in 2021 alone. With our graphene-based computing platform, we will show how low-power, low-latency and high bandwidth network security is ready for the IoT and 5G/6G future. The full system showcases the unique expertise of each consortium member in all-optical digital logic, neuromorphic computing, memory and ultra-fast clock generation. These components are realized in the 2D-Experimental Pilot Line at IHP, allowing for scalable fabrication and strengthening the EU’s supply-chain in high-performance computing. In the future, the developed platform can be deployed for applications in AI, autonomous driving and more, paving the way for computing beyond von Neumann and Moore’s Law.

    While laser powder bed fusion (LPBF) inherently allows the production of complex geometries it isn’t yet introduced to mass markets due to prohibitive cycle times and uncompetitive product precision and quality. A hybrid production where complex components using LPBF’s flexibility are built on top of conventionally manufactured substrates at near-net-shape geometry can speed up the production process dramatically, especially if applied to small component volumes. global-AM aims to advance and combine existing state-of-the-art approaches, namely beam shaping, beam splitting, in-situ geometry correction, and process monitoring + control in an advanced machine concept that allows fixation of multiple substrates and laser beam positioning to produce components on a large scale. As a demonstrator, a cooling device for power electronics is chosen because it combines typical challenges in a prototypic way: complex metal geometries made from challenging materials such as copper are built on a ceramic-based substrate with a required precision in the low micrometer scale. If the technological barriers towards the demonstrator can be solved, global-AM will introduce – but not limit – LPBF to the multi-billion euro mass market of power electronics with highly attractive technological, economical, and environmental benefits To make this project successful, experts from renowned universities and world-leading companies in the disciplines of production technology, laser systems, process development/monitoring/control, and modeling, as well as powder production for advanced multi-material powders, join their efforts in close multi-national cooperation.
