Nonlinear optics and self-lensing in self-assembled quantum dots with cw driving

Quantum dots offer new and promising possibilities for device applications in the optical communication 1.3 mum wavelength range. This paper investigates theoretically, the nonlinear optics of QD, in the continuous wave regime, of thin and thick quantum dot samples to have information on transmission properties, saturation parameter, self-lensing and nonlinear refractive index change. The quantum dot material parameters used in the simulation are typical for the ones grown by Innolume. They are made of 10 layers of InAs quantum dots inside GaInAs quantum wells with size and composition of the dots such that the peak of the emission is around 1280 nm. The saturation is shown to follow a behavior in between one for dominantly homogeneously and inhomogeneously broadened medium.
