The high device performance is achieved. The maximum continuous-wave output power of large aperture device with active diameter up to 400 m is as high as 1.41 W at room temperature. The low threshold current is only 0.5 A  which is lower than that of the conventional device with three quantum wells. 2006 Elsevier B.V. All rights reserved.
