Abstract
We demonstrate all-fiber passively mode-locked optical frequency comb source at 1.55 μm stabilized to the absorption line of the hydrogen cyanide. With reduced cavity length 169 MHz fundamental repetition frequency, 111 fs pulse duration and 44 nm wide optical comb were obtained. Frequency of the optical comb was tied to the frequency stabilized DFB laser diode Absolute stability of the single comb line was measured to be 9e-9. We expect that stability of 1e-10 within the whole comb bandwidth can be obtained with proposed configuration.
