Title: Two-dimensional laser array
Inventor: YAN OPUSHIYOORU
IPC: H01S5/40
Filed: 1989-02-27
Abstract: PURPOSE: To reduce the starting current of a semiconductor diode laser array by completely isolating the active region of one-side group from the active region of the other group by one of closing layers in a semiconductor diode laser. CONSTITUTION: The active region 3 of one-side group located inside a plane V is completely isolated by one of closing layers 2, 4 from the active region of the other-side group inside a plane W. Since the active region 3 inside one group is more completely isolated by a closing layer, namely by the layer 4 for the group inside the plane V and the layer 2 for the group inside the plane W, the threshold current of a device is relatively small. It stems from a fact that there is not parasitic radiation outside the active region and that radiation does not leak from the active region.
