Deskripsi
Abstract The generation of a 24‐fs fibre‐coupled electro‐optic‐modulation (EO) comb at 1.5 μm with a 25‐GHz repetition rate, which is the shortest pulse, is demonstrated. The authors also generated a 2/3‐octave spanning supercontinuum spectrum using precise dispersion‐controlled silicon nitride waveguides. This method can open new horizons to generate a compact and robust carrier‐envelope‐offset‐locked EO comb.
