Abstract
A photonic integrated circuit extended cavity passively mode-locked semiconductor ring laser with two saturable absorbers in a symmetric ring geometry fabricated using an InP generic integration technology platform is presented for the first time, to the best of our knowledge. The laser emits 1.4 ps short optical pulses with a time-bandwidth-product of 0.96 (Gaussian-shaped pulses) at a fundamental repetition rate of 23.3 GHz. The laser exhibits a beat-note line width of 80 kHz, corresponding to a pulse-to-pulse timing jitter of 31.7 fs. The emission is centered at 1570 nm and maximum spectral bandwidths amount to 10.2 nm (−3 dB) and 19.7 nm (−20 dB).
