Abstract
This investigation experimentally demonstrates tunable optical group delay in a 1.3m quantum dot vertical-cavity surface-emitting laser (QD VCSEL). The QD VCSEL is fabricated on a GaAs substrate. Tunable delays are achieved by varying the bias currents, and the maximum delay of 42 ps at 10GHz has been demonstrated at room temperature.
