Photon-X Spectrum Lab

Photon-X Spectrum is an advanced research unit dedicated to the development and application of next-generation photonic technologies at the micro and nanoscale. The laboratory’s activity focuses on two major and complementary directions:

1. The development of new techniques, methods and protocols for advanced imaging and spectroscopy at micro- and nanoscale.
2. The elaboration of computational photonics methods. On the experimental side, the laboratory aims to design and implement high-resolution optical characterization techniques, methods, and protocols intended for investigating complex biological systems, as well as advanced materials, with applicability in biomedicine, nanotechnology, and materials science. Additionally, the laboratory seeks to apply these techniques in high-impact applications in the aforementioned fields, either within optical correlation approaches or in tandem with non-optical characterization techniques, in order to elucidate the complex physico-chemical properties of the studied samples and the interdependencies that exist between them. On the theoretical and computational side, the lab develops tools for modeling photonic phenomena that occur at the micro and nanoscale, contributing to the understanding of fundamental mechanisms behind light–matter interactions. In parallel, methods are being developed for the processing, classification, and augmentation of experimental data by integrating modern machine learning and artificial intelligence techniques, with the goal of improving the precision and efficiency of photonic investigations. In this context, special emphasis will be placed on exploiting the spectral, temporal, and polarization properties of optical signals, in addition to their amplitude and phase. Through its interdisciplinary approach, the lab serves as a bridge between physics, engineering, life sciences, and materials science, promoting innovation in applied photonics and micro/nanoscale optical characterization. Photon-X Spectrum, founded in 2025, benefits from infrastructure developed or acquired by CS1 Dr. Ștefan G. Stanciu through research projects previously coordinated at Politehnica University of Bucharest, within the Center for Microscopy, Microanalysis and Information Processing. Among these are two prototype platforms for multimodal imaging and spectroscopy developed under Horizon 2020 Attract projects: HARMOPLUS and RO-NO-2019-0601 MEDYCONAI, coordinated by Ștefan G. Stanciu. These multimodal systems bring together a broad family of optical investigation techniques, operating primarily through laser radiation excitation — both continuous wave and pulsed — to exploit conventional and nonlinear optical effects. Cutting-edge imaging techniques such as re-scan microscopy, image scanning microscopy, and others are enhanced by PC-based optical data deconvolution platforms (e.g., Huygens SVI) and by developments in optical data processing and analysis using machine learning and AI methods.
