The electrical and optical performance characteristics such as threshold current  efficiency  emission wavelength  and output power are measured under continuous wave (CW) condition at room temperature. The maximum output power is up to watt regime at wavelength of about 980nm. The temperature characteristics of the device are investigated experimentally in detail. The variation in lasing threshold current with temperature is studied. The characteristic temperature T0 of the device is derived  and the value is about 211K. Such a high characteristic temperature T0 of threshold current can lead to good temperature sensitivity of the device. At the same time  the lasing spectrum characteristics with temperature are also measured. The wavelength shift with temperature is just about 0.06nm/K. From the measured results  it is shown that the device can still operate at high temperature condition.   The effect of blocking layer of Al2O3 on thermal stability and electrical properties of HfO2 dielectric films deposited on SiGe layer 期刊论文  OAI收割 MICROELECTRONIC ENGINEERING, 2008, 卷号: 85, 期号: 9, 页码: 1888-1891 Cheng, XH; He, DW; Zhaorui, SR; Yu, YH; Shen, DS 收藏  |  浏览/下载：18/0  |  提交时间：2012/03/24 INTERFACIAL CHARACTERISTICS  GATE DIELECTRICS  OXIDATION   High power vertical cavity surface-emitting laser with high reliability (EI CONFERENCE) 会议论文  OAI收割 Optoelectronic Materials and Devices II, November 2, 2007 - November 5, 2007, Wuhan, China Changling Y.; Guoguang L.; Chunfeng H.; Li Q. 收藏  |  浏览/下载：18/0  |  提交时间：2013/03/25 High-power vertical-cavity surface-emitting lasers with InGaAs/GaAs quantum well active gain region are investigated. By using AlAs oxidation technology  the devices have been fabricated in experiment  and the characteristics of the device are carried out at room temperature. The 300m-diameter VCSELs have the maximum room temperature continuous wave (CW) optical output power of about 1.1W  and the threshold current of the device is about 0.46A. The life test of the device is carried out in constant current mode. The life test of 300-m diameter lasers shows that the average lifetime is about 1800h at 80C. The device degradation mechanism is also discussed in detail.
