초록

The prosperity of modern society is heavily depending on communication technology. Communication is now expanding its roles from personal convenience to social/industrial functioning. Photonics was first introduced to communication in longdistance transmission area since it provided wide bandwidth cost-effectively. However, nowadays, photonics is not only a harmonious collaborator with electronics, but has its own exclusive playgrounds in various parts of communication. Limit-zero network pursues a network that can provide abundant capacity and efficiency using very limited resources. Photonics is the most promising candidate to accomplish the goal. In this article, we review the current status and predict the future contributions of photonics to limit-zero network.
