This 21.5-GHz colliding-pulse mode-locked laser cavity is defined by two on-chip reflectors incorporating intracavity phase modulators followed by an out-of-cavity SOA as booster. Under certain operating conditions, an ultra-wide spectral bandwidth is achieved along with an autocorrelation trace confirming the mode locking nature exhibiting a pulse width of 0.35 ps. The beat note RF spectrum has a linewidth of sub-MHz and 35-dB SNR.7application/pdfeng© SPIE, 2017Photonic integrated circuitsMode-locked lasersOptical frequency comb generationUltrafast pulseresearch articleÓpticahttps://dx.doi.org/10.1117/12.2264930open access102420A-1102420A-7Proceedings SPIE 10242, Integrated Optics: Physics and Simulations III (May 17, 2017)10242CC/0000026987
