The journey leading to the era of the 5th generation mobile and fixed networks, 5G and F5G, has witnessed ground-breaking innovations in optics and photonics. For the journey ahead, we are facing two grand technical challenges, the communication capacity limit imposed by the Shannon theorem and the slowing down of the Moore’s law. To address these challenges, our global optical communications community is exploring innovative network architectures, system designs, optical and DSP technologies, and photonic integrated circuits to continue reducing the cost and energy consumption per information bit. In addition, our community is broadening the application space of optics and photonics in areas such as display and sensing. In this talk, we will review emerging optical innovations for communications and beyond in the exciting era of 5G and F5G. Future perspectives will also be discussed.
