ABSTRACTIn this paper an overview is presented of results obtained with mode-locked semiconductor laser systems that are monolithically integrated using a standardized photonic integration platform based on InP. The laser systems are operating around 1550nm. In this technology platform the basic components that form the laser circuits such as amplifiers, passive waveguides and filters, as well as the semiconductor processing are standardized. Several of the possibilities that such a standardized technology offer are demonstrated by a number of examples of realized devices such as low repetition rate mode-locked lasers, a stabilized comb system and a wide frequency comb source.

Photonic integrated circuit implementation of a sub-GHz-selectivity frequency comb filter for optical clock multiplication

“…From a practical perspective, on-chip implementations of optical clock sources, e.g. integrated mode-locked lasers (MLLs) [14][15][16][17] and optically-pumped nonlinear micro-cavities [18,19], are highly desirable for many applications as an ultimately stable and compact solution for providing high quality pulses at low power consumption. They are excellent candidates for generating short optical pulses at high repetition rates, overcoming the limitation of fibers on cavity length.…”
