We demonstrate a III-V-on-silicon-nitride mode-locked laser through the heterogeneous integration of semiconductor optical amplifier on passive silicon nitride cavity using technique micro-transfer printing. Specifically, we explore impact gain voltage and saturable absorber current locking stability tunable laser. By manipulating these parameters, control spectrum across wide range wavelengths spanning from 1530 nm to 1580 nm. Furthermore, implement an optimization approach based Monte Carlo analysis aimed at enhancing mode overlap within region. This adjustment enables achievement emitting 23 while maintaining defined 10 dB bandwidth for pulse repetition rate 3 GHz.
