Abstract
Recent advances in the techniques used in optical communication1 and optical logic2 have underscored the importance of sources of fast high-power optical pulses. Appropriate pulses are often provided by a mode-locked semiconductor laser followed by an erbium-doped fiber amplifier. Here we describe an alternative approach in which a high-power semiconductor amplifier is integrated onto the source laser chip that produced 25-ps pulses with a peak power of 350 mw at a repetition rate of 1 GHz.
