Title: Laser and Microscope Development for Deep Brain Imaging with Cellular Resolution

Abstract: 

Optical methods provide high-resolution, non-invasive imaging of neural function in the intact brain. The major technology used for cellular-level imaging deep within scattering tissue is multiphoton microscopy, which provides intrinsic optical sectioning capability due to the nonlinear excitation confinement in three dimensions. Even with recent progress, the deepest multiphoton microscopy imaging today cannot penetrate a fifth of an adult mouse brain in vivo, and non-invasive deep-tissue imaging is recognized as a grand challenge in many biomedical fields such as neuroscience, immunology and cancer biology.  This talk will give an overview of innovations in femtosecond-laser and microscope technologies that enable video-rate imaging of neural activity at a depth of 1 mm in the brain of awake mice, and plans to extend the depth to beyond 2 mm, which will allow imaging of neural activity well below the cortical surface in unperturbed mouse brains.

Title: Stability in Dynamic Networked Systems

Abstract: 

The stable functioning of the infrastructure of our modern society is key for our life. This infrastructure is typically organized in various networked systems, including communication networks, in  particular optical communication, transport, or power grids etc. which are strongly interwoven. They are designed very efficiently, but they are also sensitive concerning strong perturbations, as terrorist attacks on that cybersystem or extreme climate events. An important part of modern infrastructure are power grids, which are characterized by multistability. For them, the strongly ongoing transition to distributed renewable energy sources leads to a proliferation of dynamical actors. The desynchronization of a few or even one of those would likely result in a substantial blackout. Thus, the dynamical stability of the wanted synchronous state has become a leading topic in power grid research, in particular for rather strong perturbations where traditional linearization-based approaches are not appropriate. To treat this problem, we firstly discuss the concept of basin stability covering strong perturbations and its estimation even in high-dimensional systems and identify most vulnerable motifs in power grids.

Considering the vulnerability of power grids against extreme wind loads and, consequently, increasing its robustness to withstand these events is of great importance. Here, we combine adetailed model of the climatic drivers of extreme events, and a cascadable model of the transmission network to provide a holistic co-evolution model to consider wind-induced failures of transmission lines in the Texan electrical network. The proposed approach could be a tool so far missing to effectively strengthen several kinds of infrastructure networks against further risks even under limited knowledge.

Title: Phase Imaging: the Role of Transport of Intensity and Phase

Abstract：

Phase imaging is crucial to determining the profiles of transparent phase objects, as well as the surface topography of opaque objects. Various methods exist for recovering phase, such as the GS algorithm, holography, fringe projection, ptychography, etc. Transport of intensity is a non-interferometric technique that can find the unwrapped phase, and is increasingly being used in many applications, such as quantitative phase imaging, metrology, microscopy for bio-applications, wavefront sensing, etc. Equally important is the transport of phase which is coupled with the transport of intensity. In this talk, we will discuss the basics of transport of intensity and phase equations (TIE, TPE), including their applications in digital holography (DH), to retrieve the unwrapped phase and hence the topography of 3D objects, such as fingerprints. Both iterative and non-iterative versions of the TIE (with TPE) will be discussed, along with its connection to multi-wavelength digital holography.

Title: Free-form Nanostructured Optical Fibers for Laser Systems

Abstract:

Free-form nanostructured optical fibers are a new class of optical fibers enabling flexible engineering of optical properties. Their cores are composed of thousands of silica and doped silica nanorods arranged to form an arbitrary effective refractive index distribution. Since the nanorods are smaller than the wavelength, the optical response can be described using effective medium models. This approach offers new possibilities for engineering the optical properties of fibers while maintaining compatibility with existing fiber systems. We discuss the performance of the active nanostructured fibers, including their application in ultrafast laser systems. Finally, we outline current technological challenges and future developments, with particular emphasis on 3D printing of fiber preforms and deep learning algorithms for optimization of fiber parameters.

Title: Computational imaging with metasurfaces

Abstract:

As traditional digital computing approaches physical scaling limits, the demand for high-speed, energy-efficient processing has driven a resurgence in analogue optical computing. Metasurfaces have emerged as a powerful platform for this as they are capable of performing complex mathematical operations and multidimensional light manipulation directly in the passive optical elements.

In this talk, I will discuss our recent work on metasurfaces for computational imaging, including multifunctional imaging with metasurfaces for optical domain image processing and their integration with compressive sensing and event vision sensors for lightweight analogue processing. These hybrid systems offer a pathway toward low-latency vision systems with applications in intelligent vision systems.
