Abstract
Pulse trains with repetition rates as high as 80-200GHz were obtained at 1.55μm, using rational harmonic mode-locking with an erbium doped fibre laser. A fundamental repetition frequency (fosc) of 40GHz was first generated by applying a 40GHz modulation frequency to an LN intensity modulator in the fibre cavity, in which the longitudinal mode spacing (Δf) was 1.5MHz. By rationally detuning the modulation frequency by Δf/n, the authors succeeded in obtaining a repetitive oscillation of (nfosc++Δf). The maximum frequency was 200GHz, at which n corresponds to 5.
