Abstract

We present an optical-electronic approach to generating microwave signals with high spectral purity. By overcoming shot noise and operating near fundamental thermal limits, we demonstrate 10 GHz signals that have timing deviation from an ideal periodic sine wave of only 4 parts per million even after integrating the noise over 10 billion cycles.
