Title: The Innovations of Roger Carroll

Introduction

Roger Carroll is a notable inventor based in Ottawa, Canada, recognized for his contributions to optical communications technology. With a total of five patents to his name, Carroll has made significant advancements in the field, particularly in frequency domain multiplex optical transmission.

Latest Patents

One of Carroll's latest patents involves a transmitter that utilizes a complex mixer to generate a single I analog drive signal and a single Q analog drive signal. This system employs a multi-dimensional optical modulator to modulate an optical carrier light, producing a modulated optical signal for transmission. Alternatively, another design features a complex mixer that generates two I analog drive signals and two Q analog drive signals, which are then used by a multi-dimensional multiple-electrode optical modulator. In both cases, the optical carrier light is produced by a single laser, ensuring that the frequency components of the data signals are located in different portions of the spectrum of the modulated optical signal. Additionally, Carroll has developed a method for transmitting a data signal in an optical communications system, which includes processing the data signal to generate an analog drive signal through a first non-linear operation, allowing frequency components to lay in at least two separated spectral bands.
