Superconductor-based photon detectors
Research
Our research focuses on superconducting resonators, with a particular emphasis on microwave kinetic inductance detectors (MKIDs) and their applications in various fields, including X-ray, IR, and THz detection. We explore the fundamental physics of superconducting materials, investigating how factors such as geometry, material composition, and environmental conditions influence device performance. A key aspect of our work is understanding the effects of magnetic fields on superconducting resonators, particularly in the context of improving their resilience and functionality in challenging operational environments. By developing novel designs and fabrication techniques, we aim to enhance the capabilities of MKIDs and expand their applicability in advanced sensing technologies.
