All-Optical Regeneration for Global-Distance Fiber-Optic Communicationsng the basic principle of optical regeneration in lightwave systems, we describe the state of the art in experimental implementation. We also discuss the alternative offered by electronic regeneration, and highlight the advantages of the all-optical approach, with its technology challenges.

Intentional

Optical Twist properties and experimental realization of both Gaussian and non-Gaussian twisted beams are described with illustrative physical examples. As an application, the role of the twist in beam quality is elucidated. The relation of the twist to optical vortices and angular momentum is addressed. Some unsolved issues are pointed out.
