Abstract:
A surface emitting laser array comprising a plurality of surface emitting laser devices each having a semiconductor layer containing a first reflection mirror, an active layer, a current confined portion and a second reflection mirror. The laser array further comprises a first metal material layer for dissipating heat formed through a first insulating layer on the semiconductor layer and a second metal material layer for injecting current into the active layer formed through a second insulating layer on the first metal material layer. The first metal material layer is commonly shared by the plurality of the surface emitting laser devices.
