Fiber-Optical Coupling

Abstract

In modern optical communication systems, it is of the highest importance to transmit as much optical power from the transmitter to the receiver. It seems that future systems will not be that strongly dependent on good optical waveguides. Actually, even after 25 years of existence of low-loss glass fibers, the coupling efficiency remains the biggest concern of the system engineers. In this chapter, the most important principles of the optical coupling that are relevant for engineers working with this topic are discussed.
