Robust Gigahertz Repetition Rate Optical Frequency Combs

We, along with the help of Menhir Photonics and Octave Photonics, have prototyped a ruggedized, compact, fully stabilized breadboard optical frequency comb based on commercially available components to analyze the stability, efficiency, and benefits of high repetition rate optical frequency combs in relation to lower repetition rate counterparts.

Transferring the Long-Term Stability of a GPS-Disciplined OCXO to Vescent’s FFC-100 Optical Frequency Comb by Repetition Rate Locking

We demonstrate a straightforward method of locking Vescent’s fiber frequency comb (FFC-100) repetition rate to any user-supplied RF oscillator.
To demonstrate the power of this technique, we lock the FFC-100 to an SRS FS740 GPS-disciplined oven-controlled crystal oscillator (OCXO) and show that the superb long-term frequency stability of the SRS FS740 is transferred faithfully to the frequency comb modes while retaining the short-term stability characteristic of the free-running comb tooth linewidths.

Integrated f(CEO) Phase Noise of 280 mrad RMS in a SESAM-based Frequency Comb Supporting a Fractional Frequency Instability of 1.3x10^(-17) at 1 s


Vescent presents our latest generation SESAM mode-locked Er:fiber frequency combs exhibiting a dramatically reduced phase noise in the carrier-envelope offset frequency (fceo) without sacrificing on environmental ruggedness and industry-leading compactness associated with our previous generation SESAM-based frequency combs.
