Photonic Transceivers for Secure Radio Frequency Communications and Radar

Jason Chou | 19-ERD-039

Project Overview

We developed a powerful library of simulation models that can be used to design and predict performance of an array of photonic systems. Through extensive experimental testing, we successfully validated the highest risk models. We then used these models to design a high-performance transceiver for X-band communication. The experiments, along with a series of matching simulations, led to parameter constraints that guided the design process to maximize XPM-induced gain, probe visibility, and probe transmission, towards the goal of maximizing the signal-to-noise-and-distortion ratio.

Mission Impact

The novel photonic technologies that we developed for high-fidelity radio frequency (RF) signal detection and generation systems directly impact the mission of Lawrence Livermore National Laboratory’s National Ignition Facility, for developing advanced target diagnostics, as well as other Department of Defense applications. In addition, the research supports the Laboratory’s core competency in lasers and optical science and technology.
