Paper Abstract

Transmission of analog diagnostic information over fiber lightguides is a frequent practice where the signal source is a single transient event and the data link is in the kilometer length range. Certain adverse test environments, for example, require use of the data links to remotely acquire transient microwave-frequency diagnostic data. In such cases, the optical signal intensity at the receiver is often too low for the large bandwidth, wide dynamic range detection that is needed. Thus, it is desirable to amplify the signal while maintaining high fidelity. A convenient method of achieving direct in-fiber linear amplification has been developed and demonstrated that uses backward stimulated Raman scattering. In this chapter we will explain briefly the physical process, present some experimental observations, and discuss the problems related to its practical application.
