Physically Aware Agile Optical Networks

With the development of new laser sources, ber ampli ers, and other optical components, optical communication systems have undergone enormous growth and evolution in recent decades. The current trend of optical networking is to move towards dynamic, all-optical networks. In all-optical networks, information signals are transmitted from source to destination totally in the optical domain, without the usual optical-electrical-optical conversions at intermediate nodes. New challenges and opportunities emerge in different layers of the optical network architecture in this transition process.
