Develop smart, low-cost and energy-efficient fiber sensors

Tue, 21 Oct 2025 00:00:00 +0000

Developing smart, low-cost and energy-efficient fiber sensors is crucial for making advanced sensing technologies accessible and sustainable. Traditional optical sensors often require expensive materials and high-power interrogation systems, limiting their large-scale deployment. By focusing on cost-effective fabrication and low-energy operation, our research aims to enable widespread environmental monitoring, structural health diagnostics, and biomedical sensing with minimal resource use. The main goals are to optimize sensor design for high sensitivity and low loss, reduce fabrication complexity, and integrate efficient signal processing to support scalable, real-world applications.

Investigate extreme light-matter interactions

Mon, 20 Oct 2025 00:00:00 +0000

Investigating extreme light–matter interactions in hollow-core fibers is crucial for advancing ultrafast nonlinear optics. By confining intense laser pulses within gas- or plasma-filled microstructures, these fibers provide a unique platform to explore phenomena such as soliton dynamics and strong-field ionization under precisely controlled conditions. The main goals of this project are to unveil new regimes of nonlinear light propagation, develop compact sources of coherent radiation from the ultraviolet to mid-infrared, and enable next-generation applications in attosecond science, quantum technologies, and high-field spectroscopy.
