Advancements in Photonic Devices for Chaos-Based Communication Systems

This research project focuses on the development of innovative photonic devices utilizing chaotic waveforms to enhance optical communications. Funded by the Ministry of Education and Science, the initiative involves a multidisciplinary team from various institutions aiming to study the dynamics of semiconductor lasers under complex feedback systems. Key objectives include increasing security levels and exploring new encoding techniques. Specific tasks involve analyzing edge-emitting lasers, chaos generation in electro-optical systems, and synchronization methods for message encoding and decoding.
