Opening the THz-UV spectrum with integrated photonic-electronic systems

Research Project, 2025 – 2026

The long-term goal of the planned excellence cluster is to explore and expand the applications of the electromagnetic spectrum to support future scientific and technological advances. The project combines expertise in nanoelectronics, terahertz technology, photonics, microsystems, solid-state physics, and nanotechnology to explore the entire spectrum from terahertz to ultraviolet. Cross-spectrum innovation, achieved by integrating electronics and photonics across a four-decade wavelength range, enables interdisciplinary research and breakthroughs in sensing, communication, and control systems. At the core of this initiative are fundamental research questions:Can integrated photonic systems generate spectrally pure signals far beyond the limits of traditional RF electronics?Can optical clocks be used to synchronize electronic systems, enhancing digitization resolution and enabling higher performance in signal processing conversion?Is it possible to realize chip-scale UV lasers?How can the best in-class materials be combined effectively for wafer-level integration?Can integrated photonic-electronics enable access to uncharted regions of the THz spectrum?These questions define a technological frontier aligned with Sweden’s innovation priorities. The cluster connects diverse disciplines to establish a new paradigm in integrated electronic-photonic systems, supporting the European Chips Act and advancing excellence.
