Talk Title: Pushing the Edge of the Cosmic Frontier with JWST

Abstract
The James Webb Space Telescope (JWST) launched in December 2021, first started collecting data in June 2022, and is already revolutionizing our understanding of the distant Universe. With it's large segmented mirror, and optimization for infrared wavelengths, JWST was designed to detect and characterize some of the first galaxies to form in our universe and investigate how galaxies then evolve over the age of the Universe to the present day. In this talk, I will present how JWST has pushed our cosmic frontier beyond what was possible with Hubble and share some early results from extragalactic deep surveys and their implications for our understanding of the early universe.

Jeyhan Kartaltepe is an astrophysicist in the School of Physics and Astronomy at the Rochester Institute of Technology. She was born in San Antonio, Texas, then moved to different parts of the US for her BA, MS, PhD, and postdoc before settling in Rochester, New York. She is an expert in the area of galaxy formation and evolution and is interested in understanding how the first stars and galaxies in the universe formed and how various physical processes shaped their transformation into today's galaxies. She is a PI of COSMOS-Web, the largest James Webb Space Telescope program to be observed in its first two years of operations, which is mapping out a large area of the sky in the near- and mid-infrared to study how galaxies in the early universe formed in relation to structures on large scales. She is also a leading co-I on the CEERS program, one of the first programs to obtain observations.

Talk Title: Attosecond pulse generation: strong laser fields and extreme nonlinear optics

Abstract
Observing the smallest nature's structures with nanoscale or even atomic resolution has improved our understanding of our world. However, many important material properties are not static. For instance, the motion of atoms in molecules occurs in the femtosecond domain and pure electronic motion can happen much faster, on attosecond time scales. This is why the three Nobel Laureates in Physics 2023 have been recognized for their experiments that gave humanity the tools to explore the realm of electrons inside atoms and molecules. In this talk, I will give an introduction to the physics and technology behind the process of high-order harmonic generation employed for table-top XUV sources and attoseocnd beamlines. We will see that many developments in ultrafast laser technology are directly motivated by their use in attosecond science. Potential applications of attosecond pulses will be identified, touching upon various areas.

Bio
Anne-Lise Viotti received a double engineering degree from Institute of Optics (IOGS) in France and the Royal Institute of Technology (KTH) in Sweden, where she also obtained her PhD in laser physics in 2019. In 2020, she was awarded a postdoctoral fellowship from the Swedish Research Council, to pursue research between Lund University and the facility of DESY in Germany. She is currently an assistant professor in the Attosecond Physics group at the department of Physics of Lund University. Her research interests focus on ultrafast optical sources based on high power lasers for high-order harmonic generation and attosecond spectroscopy in the soft x-ray regime.

Talk Title: Towards the Development of On-Chip Spectrometer and Spectroscopy

Abstract
Vibrational spectroscopy has emerged as a powerful tool for biomedical diagnostics and environmental monitoring, offering rapid and accurate sample analysis. However, conventional methods, which involve sending samples to centralized labs, often result in significant delays in obtaining results, thereby limiting its potential impact in critical applications. There is a growing demand for miniaturised and efficient devices that can be used at the point of care and in remote locations where environmental sensing is crucial. This presentation will focus on the development of various integrated optical device platforms for on-chip spectrometers and spectroscopy, highlighting their immense potential for both biomedical and environmental applications. Specifically, various integrated device platforms utilising heavy metal oxides, chalcogenides, and germanium on silicon will be discussed, enabling compact and portable solutions. Furthermore, the presentation will showcase recent spectroscopic approaches tailored for targeted biomarker analysis. This includes the application of machine learning to collected spectra, the integration of different spectroscopic modalities for enhanced analysis, and methodologies for correcting atmospheric interference.

Talk Title: Programmable Photonics

Abstract
In the past decades, photonic integrated circuits have become entrenched as a key enabling technology for fibre-optic communication. They make it possible to integrate a combination of optical and electrical functions on the surface of a chip, which can be fabricated with the same technologies used for microelectronics. But just like electronic chips have found applications in many more domains than computing, we expect photonic chips to find their way into very diverse application fields, such as sensors, lidar, free-space communication, microwave signal processing and biomedical diagnostics.
One aspect in which photonic chip technology is less advanced than its electronics counterpart is programmability: photonic chips today are fabricated for a single purpose, and each new iteration or experiment needs a new chip design. By making photonic chips programmable, like we know from field-programmable gate arrays (FPGA) in digital electronics, we can accelerate the development and innovation cycles, opening up the capabilities of photonic chips to a much broader engineering community.
We will discuss the state of programmable photonics today, the results of recent expertiments at Ghent University - IMEC, and where the key challenges are to realize the technology platforms that can truly enable multi-purpose photonic processors.

Bio
Wim Bogaerts is a professor in the Photonics Research Group at Ghent University and the IMEC nanotechnology research center in Belgium. He completed his PhD in 2004, pioneering the use of industrial CMOS fabrication tools to build photonic circuits. Between 2000 and 2010, he was the driver behind the buildup of IMEC's silicon photonics technology. In parallel, he started developing design automation tools to implement complex silicon photonic circuits. In 2014, he co-founded Luceda Photonics, bringing the design tool IPKISS to the market. In 2016 he won a research grant from the European Research Council, and since then he is again full-time at Ghent University - IMEC, focusing on the challenges for large-scale photonic circuits and the new field of programmable photonics. He is an IEEE and OPTICA Fellow, and senior member of SPIE.
