Improvements of Electro-Optical Frequency Comb Implementations
In this talk I will review advances in optical frequency comb implementations of so-called electro-optical (EO) frequency combs, based on phase and intensity modulation of a stable carrier. Stable frequency comb operation spanning over an octave and subsequent self-referencing was recently achieved by the NIST group (Beha et al., 2017). This inspires different implementations of EO frequency combs, including fiber based systems and photonic integrated circuit approaches.
