Abstract

The refractive index, capture rate and sensitivity of quantum dot laser devices to optical feedback were discussed. The line-width enhancement factor and the relative intensity noise spectrum of the devices were also discussed. The line-width enhancement factor for the devices was measured using the Hakki-Paoli method. It was found that the devices possessed symmetric gain curves and also demonstrated small phase-amplitude coupling.
