The goal of this topic is to bring together researchers from the distinct disciplines of environmental sensing, frequency metrology, fiber-optic telecommunications equipment providers, and network operators. While fiber sensing has been an active research and product topic for decades, recently, there has been a considerable increase in the successful applications of data recorded using the existing fiber grid for a broad variety of geophysical and sensing goals. Optical fibers make excellent sensors, as the slightest fiber strain can measurably alter the polarization, frequency, and phase of the guided optical field. The ability to measure such changes has opened up a multitude of applications from infrastructure monitoring to geophysical exploration. However, it is still missing a clear path on how the scientific community and the network operators could benefit from each other’s expertise. This session aims to continue the early-stage discussion on how telecommunication operators and researchers can work together to fully exploit the existing fiber infrastructure for novel sensing applications that would co-exist with telecom operations.
Development and deployment of Free Space Optical Communications (FSOC) has surged in recent years with optical satellite interlinks (OSILs) becoming a critical component in next-generation satellite constellation networks. Beyond OSILs, FSOC is poised to become a foundational element in networks of the future enabling higher security, faster data rates and the ability to bring connectivity to underserved locations throughout the world. Presently, FSOC is being deployed at scale by the commercial sector, while research institutions are enhancing the capability of FSOC by increasing link distances and data rates, and finding novel methods to increase the overall reliability of an FSOC network. The scope of this meeting will involve invited talks, contributed talks, and panels, with experts from industry, national labs, and academia. Specific topics will focus on space-based transceivers, high power laser sources for transmitters, Optical Ground Stations (OGS), Deep Space Optical Communications (DSOC), novel sources and FSOC for Next Gen Networks such as LiFi and 6G.
The development of optical networks and network architectures supported by multi-band (MB) systems outside conventional fiber transmission windows and space-division multiplexing (SDM) technologies is seen as one of the key enablers for cost-effective capacity upgrades to address the “capacity crunch”.

Recent advances in photonic integration, applications of novel switching solutions for high capacity optical networks supported by MB and/or SDM transmission including hollow core fibers, mitigation of signal quality degradation, transmission from O to U-band including fiber design and fabrication, propagation modeling and fundamental limits for MB transmission and SDM fibers, digital signal processing strategies and application of waveband conversion. The topic will also include a discussion on “Career Perspectives in Optical Communications and Beyond” for students and early career researchers.

The world of precision atomic and molecular quantum technologies, scientific experiments, instrumentation, and discoveries such as atomic clocks, quantum sensing and metrology, and thermal sensing, have the potential to undergo a transformation to the chip-scale much like computers of the 1950s. This transformation will unleash a wealth of new precision applications in biomedical, sensing, communications, computation, metrology and advances in fundamental physics. Photonic integration of the visible to mid-infrared wavelength range (200 nm – 20.0 µm), spanning two orders of magnitude in wavelength, will enable access to a wide range of atomic, ion, and molecular transitions and overlaps with transparency windows available in optical waveguides, optical fibers, and atmospheric and near- and deep-space propagation. Precision timing and spectroscopy, information on thermal emission properties of matter, new particle discovery, and space-based applications, and much more, will benefit from the improved reliability, scalability, and reduction in size, weight, and power brought about from new generations of integrated and fiber optic based technologies.

The confluence of an exceptional abundance of data and computational resources has enabled techniques of machine learning to revolutionize fields across computer science, ranging from image analysis and natural language processing to decision making. Neuromorphic computing is a non-Von Neumann approach to computing that is inspired by the structure and function of the human brain, which promises to run machine learning algorithms more efficiently. Following this trend, neuromorphic photonics has raised as a promising and cutting-edge technology to overcome limitations in neuromorphic computing, capable to execute intricate computations at the speed of light and with impressive energy efficiency. Diverse material technology platforms and architectures are being proposed and demonstrated to affirm the potential of this paradigm in computation. Next to discriminative AI, commonly exploited to distinguish between types of informational input, Generative AI is raising more and more prominently for its ability to mimics human creativity and therefore coming up with high-quality generated content in the forms of text, images, songs, poems, essays, just to name a few. Photonics is foreseen to support this transition to the Generative AI Era via generative photonics, inverse design, high-speed low-power computation, and more.
PSC 2024 is the right context where to discuss advances and innovations in neuromorphic photonics and also to identify the next steps towards a photonics-enables Generative AI era.
