Abstract
We present experimental and theoretical evidence of dispersive self-Q switching in hybrid III–V/SiN extended cavity integrated lasers with a frequency-selective narrow-band mirror. Although similar regimes have been previously predicted in photonic crystal lasers, our results demonstrate their occurrence in a considerably simpler and more accessible platform based on silicon photonics technology and without the need for a saturable absorber section. The measurements are accurately reproduced by a theoretical model, whose excellent agreement with experiments establishes a robust and versatile framework for analyzing and optimizing future device designs.
