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.
Anne-Lise Viotti
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.

Wim Bogaerts
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.

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.
