Abstract

We describe simultaneous generation of ultralow-noise optical pulses and microwave signal with a mode-locked fiber laser in a coupled optoelectronic oscillator configuration. We demonstrate $9.2\text{-}\mathrm{GHz}$ optical and microwave signals with the measured phase noise of $-140\mathrm{dBc}∕\mathrm{Hz}$ at $10\text{-}\mathrm{kHz}$ offset frequency. We show that the mode-locked laser in the photonic oscillator serves as a high-Q filter and is responsible for the observed low phase noise.
