Title: The Innovations of Sanjai Parthasarathi
Introduction
Sanjai Parthasarathi is a notable inventor based in Los Altos, California. He has made significant contributions to the field of optical communications, particularly through his innovative patent. His work focuses on enhancing the efficiency and cost-effectiveness of group delay compensation in optical systems.
Latest Patents
Sanjai holds a patent for a "Single channel four-port group delay compensation equalizer." This invention employs a single channel four-port WDM device to compensate for the group delay experienced by multiple wavelengths transmitted over different paths. The technology compensates for the transmission differential between two wavelengths by utilizing two distinct paths, ensuring that the fiber length for the second wavelength matches the transmission time difference. This innovative equalizer provides a unidirectional signal flow, contrasting with conventional equalizers that operate bi-directionally. By simplifying the design from multiple three-port WDM devices to a single four-port device, Sanjai's invention significantly reduces costs and the number of required alignments.
