Title: The Innovations of Carl R. Davidson
Introduction
Carl R. Davidson is a notable inventor based in Warren, NJ (US), recognized for his contributions to optical communication systems. With a total of 11 patents to his name, Davidson has made significant advancements in the field of quadrature amplitude modulation (QAM) and related technologies.
Latest Patents
Davidson's latest patents include groundbreaking work on generating higher-level quadrature amplitude modulation (QAM) using a delay line interferometer. This innovation allows for the generation of higher-level nQAM from nQAM signals through various configurations of delay line interferometers (DLIs). The technology utilizes lower-level modulators, such as BPSK and QPSK modulators, to produce binary driving signals. By selecting different parameters of the DLIs, such as free spectral range (FSR) and phase shift, the desired higher-level nQAM can be achieved. Another significant patent is the correlation-control QPSK transmitter, which employs a multi-level data modulator to produce a PDM-QPSK signal. This optical transmitter is designed to enhance spectral efficiency by reducing the signal spectrum before transmission over multiple optical channels.
