Query: Towards CW modelocked laser on chip -- large mode area and NLI for
  stretched pulse mode locking   Integrated modelocked lasers with high power are of utmost importance for
next generation optical systems that can be field-deployable and mass produced.
Here we study fully integrated modelocked laser designs that have the potential
to generate ultrashort, high power, and high quality pulses. We explore a large
mode area laser for high power pulse generation and study the various
mode-locking regimes of dispersion managed soliton pulses in net anomalous and
net normal dispersion cavities. Furthermore, we study numerically and
experimentally general properties and tunability of a fast integrated saturable
absorber based on low loss silicon nitride nonlinear interferometer. We believe
this work guides the exploration of the future integrated high power modelocked
lasers.
