In this seminar, I will present two complementary research directions that my group at DTU has developed to extend high-impact photonic sensing applications across diverse domains - from environmental monitoring and bioimaging to the central nervous system.

The first part focuses on the development of laser sources enabled by strong light–gas interactions in hollow-core fibers, generating light pulses from the deep-UV to the mid-infrared. I will show how these lasers can be uniquely combined with photoacoustics for high-resolution environmental sensing and advanced (bio)imaging. The second part will present results using soft polymer materials to create flexible, fiber-based bidirectional neural interfaces that integrate multiple functionalities and embedded local sensing elements through laser-structured patterns.
