Abstract

In this Letter we report on an all-optical-fiber approach to the generation of ultra-low-noise microwave signals. We make use of two erbium fiber mode-locked lasers phase locked to a common ultrastable laser source to generate an 11.55 GHz signal with an unprecedented relative phase noise of 111 dBc Hz at 1 Hz from the carrier. The residual frequency instability of the microwave signals derived from the two optical frequency combs is below 2.3 × 10 16 at 1 s and about 4 × 10 19 at 6.5 × 10 4 s (in 5 Hz bandwidth, three days of continuous operation).
