Abstract:
1. A light emission device comprising: a first clad layer; an active layer disposed on the first clad layer; a second clad layer disposed on the active layer; a first electrode electrically connected with the first clad layer; second electrodes electrically connected with the second clad layer, and third electrodes electrically connected with the second clad layer and are different from the second electrodes; wherein the active layer forms a first gain area by sending current between the first electrode and the second electrode, the active layer forms a second gain area by sending current between the first electrode and the third electrode, the first gain area and the second gain area extend from a one side while inclined to a vertical line of the one side in the plan view of the active layer, the second electrodes are electrically connected with a first common electrode, the third electrodes are electrically connected with a second common electrode, and the first gain area and the second gain area alternately emit light.
