Abstract

This invention teaches new types of linearization circuits, exhibiting improved broadband suppression of nonlinear distortion. These realizations do not require the use of reactive elements such as capacitors, or of active elements such as transistors, eliminating the drawbacks of prior art realizations. The linearization circuits are particularly suitable for linearizing optical sources with odd wave voltage to light transfer characteristics, such as externally modulated CW lasers. The fundamental building blocks of the linearization circuits of this invention are novel nonlinear electrical one-ports with an expansive V-I characteristic, denoted as ENLOP (Expansive Nonlinear one-Ports). The ENLOP building blocks are further embedded in linear circuits.
