Title: The Innovations of Robert L. Rosenberg
Introduction
Robert L. Rosenberg is a notable inventor based in Fair Haven, NJ (US). He has made significant contributions to the field of optical communications, particularly in the area of polarization modulation. With a total of 3 patents to his name, Rosenberg's work has had a profound impact on the efficiency and effectiveness of optical transmission systems.
Latest Patents
Rosenberg's latest patents focus on apparatus and methods employing fast polarization modulation to reduce the effects of polarization-dependent hole burning and polarization-dependent loss. These innovations involve modulating the state of polarization (SOP) of an optical signal being launched into the transmission path. The modulation occurs periodically between first and second states of polarization of at least one pair of orthogonal states. Ideally, the launched modulated signal spends equal time intervals in both states of the orthogonal pair. In one exemplary embodiment, the SOP is modulated such that it moves along a great circle on the Poincare sphere. This method aims to maintain a predetermined parameter, such as the signal-to-noise ratio, at a maximum value.
