摘要
把1.3μm波长分段吸收式脊形波导结构发光二极管进行不同温度的加速老化寿命试验,共测试248500器件小时。该器件在25℃、150mACW的平均寿命为1.2×106h,其退化激活能Ea=0.48eV;与标准单模光纤耦合后,在25℃、100mA下的光功率大于30μW,最大可大于50μW。
m wavelength ridge waveguide light emitting diodes(RWG LEDs),which have seperated absorbing area,are taken to carry out lifetest in diferent temperatures.Almost 248,500 device hours are tested.1.2×106 hrs of lifetime(MTTF)can be got under the condition of 25℃ambient temperature and 150mA CW drive current;The degenerate activated energy is Ea=0.48eV;The light power of the RWG LEDs is more than 30μW,maximum can be more than 50μW,which are got from coupled standard single-mode fibre under 25℃ and 100mA DC drive current.
