All-optical signal regenerators for ultra-high bit-rate transmission systems
01 January 2002
In this paper, we review recent developments in the field of optical regeneration for both ultra long-haul transmission and terrestrial networking applications. Different techniques (2R/3R) using nonlinear properties of materials and/or devices are proposed such as saturable absorber or InP based interferometer structures showing regenerative capabilities. Principles of operation as well as system experiments are described.
