Strong B-PHOT presence at SPIE Photonics Europe 2024

The SPIE Photonics Europe 2024 conference held in Strasbourg, France, has seen a remarkable presence of B-PHOT researchers. With a multitude of presentations delivered by B-PHOT staff, the event underscored VUB's significant contributions to the field of photonics.

The global photonics community gathered in Strasbourg last week to share insights and innovations. The comprehensive programme of SPIE Photonics Europe 2024 featured a plethora of sessions covering various aspects of photonics technology and research.
