Abstract
A surface emitting laser element array comprises a plurality of surface emitting laser elements () on a same substrate () each comprising a mesa post formed of a laminated structure including an active layer () for reducing a crosstalk between the surface emitting laser elements constituting the surface emitting laser element array, and for improving a high speed response, wherein each of the surface emitting laser elements () comprises a first electrode (), a second electrode () and a third electrode () that have a polarity different from that of the first electrode (); the first electrode () is arranged on the mesa post; the second electrode () is arranged on one surface of the substrate () same as that of the first electrode (); the third electrode () is arranged on the other surface of the substrate () opposite to that of the first electrode and the second electrode () and is provided as a common electrode of the surface emitting laser elements (); and an electric current is applied to the active layer () using the first electrode () and the second electrode ().
