Abstract
This work presents group delay measurements for a 1.3 μm quantum dot semiconductor optical amplifier at various injection currents. White-light interferometry is used to obtain group delay data spanning both ground state and first excited state transitions, ranging from 1200 nm to 1320 nm. The group delay, group velocity dispersion and existence of higher order dispersion is observed and quantified.
