Numerical modeling and parameterization of on-chip colliding pulse mode-locked lasers

摘要

The successful numerical modeling and parameterization of on-chip colliding pulse mode-locked lasers by using the simulation tool FreeTWM based on Matlab is reported. We have been able to reproduce the performance of on-chip colliding pulse mode-locked lasers with different repetition rates within the millimeter wave frequency range. We have achieved the successful simulation of a first device working around 37 GHz and the second device working around 70 GHz due to the fact that the collision in the saturable absorber located in the middle of the resonator multiply by two the fundamental frequency of 18.5 GHz and 35 GHz, respectively. The Free TWM software is a promising candidate for the simulation and optimization of on-chip colliding pulse mode-locked lasers. So, we will avoid spending time and money on fabrication process of many samples in order to obtain an optimized device.
