Simplified offset stabilization of a low-noise 1 GHz oscillator

We use the Octave Photonics Comb-Offset-Stabilization Module (COSMO) to detect ƒCEO of a Menhir Photonics 1-GHz, 1550-nm oscillator with less than 140 pJ of pulse energy (<140 mW average power). A Vescent Photonics SLICE-OPL offset-phase-lock controller provides the feedback signal to the oscillator and establishes a tight lock with only 0.26 radians of residual phase noise. Together, this demonstrates a simple method for building compact and reliable frequency comb sources at GHz repetition rates.
