MENHIR 1550 - Building a frequency-comb

In this demonstration, the Octave Photonics Comb-Offset-Stabilization Module (COSMO) was used to detect the carrier-envelope-offset frequency fCEO of a Menhir Photonics 1 GHz, 1550 nm oscillator with less than
140 pJ of pulse energy (i.e. 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.
