Abstract
The linewidth floor of a DFB laser observed in the linewidth/optical output power relation is an unresolved issue. It is found experimentally that the linewidth floor and linewidth rebroadening occurs in conjunction with spatial hole-burning along the lasing axis. Tailoring the current distribution along the lasing axis by using a three-terminal DFB laser can reduce the linewidth floor
