RF beat note analysis of a semiconductor optical frequency comb — •Duc Nam Nguyen¹, Dominik Auth¹, Quentin Gaimard², Abderrahim Ramdane², and Stefan Breuer^1,3 — ¹Institute of Applied Physics, TU Darmstadt, Darmstadt, Germany — ²Centre de Nanosciences et Nanotechnologies, Palaiseau, France — ³John A.

We experimentally study the RF beat note and optical spectra evolution of a frequency-modulated near-infrared semiconductor comb laser. We show and explain a transition towards stable optical frequency comb generation in dependence on the electrical biasing conditions.
