Title: Christopher E Sunderman: Innovator in Optical Signal Processing
Introduction
Christopher E Sunderman is a notable inventor based in Rockville, MD (US). He has made significant contributions to the field of optical signal processing, particularly in the area of radio frequency (RF) output quality. His innovative work has led to the development of a patented method that addresses harmonic distortion in RF signals.
Latest Patents
Sunderman holds a patent titled "Even-order harmonic cancellation and increased RF gain using dual-output Mach-Zehnder modulator with two wavelength input." This invention presents a method and system for processing analog optical signals to produce a single RF output free from even-order harmonic distortion. The process involves inputting two analog optical signals of different wavelengths into a dual-output Mach-Zehnder modulator (MZM). One wavelength is high-biased while the other is low-biased. The complementary high- and low-biased wavelengths are then output from each arm of the MZM to a multiplexer, which filters out unwanted wavelengths. The signals are subsequently passed to a pair of photodiodes, where the photocurrents are differenced to yield the final RF output. This innovative approach ensures that all components of the photocurrent, except for the fundamental and odd-order harmonics, cancel each other out, resulting in a high-quality RF output free from harmonic distortion. Sunderman's patent portfolio includes 1 patent.
