摘要
发光二极管(LED)是卫星光通信系统中重要的光源部件,它的工作性能直接影响着光通信系统的可靠性。对粒子辐照条件下LED器件的少数载流子寿命和输出光功率变化进行了深入的理论分析,依据理论分析展开数值模拟计算。结果表明,提高LED有源区Zn元素掺杂浓度可有效降低少数载流子的辐射寿命,在提高LED输出功率的同时有效提升器件的空间抗辐射性能。
The light emitting diode（LED） is one of the key components in the optical satellite communication system,whose performance determines the reliability of the communication system.The theoretical analysis of the minority carrier′s lifetime and output power of LED device under particle radiation is made.The numerical simulation is also done based on the theoretical analysis.The calculation results prove that the increase of the doped Zn density in the active area of LED can effectively decrease the radiative lifetime of the minority carrier and it also can improves the LED′s anti-radiation performance while heightening its output power.
