Abstract :
A compact, passively fundamental-modelocked Er,Yb:glass laser with 25 GHz pulse repetition rate tunable over the C-band is demonstrated. By combining this laser with a dynamic gain equaliser, a flat optical spectrum with up to 36 discrete channels with a 25 GHz spacing and an optical signal-to-noise ratio >40 dB was generated.
