Photonic Continuity: Sustainable Wired and Wireless Photonics from kilobits per second (kbps) to Petabits per second (Pbps)

Optical wireless communication has been present for more than half a century, from home remote control to data laser link between satellites, without mentioning the military applications which have clearly understood this technology’s potential. The paper presents a general view of this field, including fiber optic development up to passive optical network, and then focuses on the latest addition in this area - Fiber Wireless (FiWi) - offering a very high-speed wireless solution and the opportunity of a sustainable all-optical network (AON).
