Eszter Udvary Gerhatne is an associate professor of the Department of Networked Systems and Services, Faculty of Electrical Engineering and Informatics, BME. She is a member of the Mobile Communications and Quantum Technologies Laboratory.
Dr. Udvary’s research interests are in the broad area of optical communications focusing on the physical layer of the networks. Her research activity includes Microwave Photonics (MWP), Radio over Fibre (RoF), Radio over Free Space Optic (RoFSO), optical access network, Visible Light Communication (VLC), and quantum communication.
She investigated the application of multifunctional semiconductor optical amplifiers in optical access networks, and she is deeply involved in optical approaches for future mobile systems. This competence is very useful in the study of photon-based quantum key distribution systems. In addition to fiber optic solutions, she has several indoor optical wireless communication results, which lead to the development of the free space quantum links. Recently she has been focusing on the efficiency improvement of quantum random number generators.
She has been the Hungarian leader of the H2020 FIWIN5G - FIber-Wireless Integrated Networks for 5th Generation delivery project, COST Actions (Newfocus, iMWP); and she involved in several Hungarian research projects (HunQuTech, EFOP, OTKA.)
