摘要

研究了商用1300nm激光二极管在瞬态辐照下的性能，验证了光数据链路在辐射环境中的应用。采用Nd:YAG激光模拟无永久性损伤的辐照。选择了两个特定波长:1064 nm允许选择性激发模拟单个粒子瞬态效应的激光腔和532 nm与整个器件相互作用。首先观察二极管的时间响应，并将其形状解释为器件物理结构的函数。然后给出了扰动后恢复平衡时间随偏置电流的变化规律。然后讨论了用于模拟和数字应用的光链路的限制。

Physical mechanisms involved during transient irradiation of a 1300 nm laser diode

The behavior of a commercial 1300 nm laser diode under transient irradiations is studied to validate the use of an optical data link in a radiative environment. A Nd:YAG laser is used to simulate the irradiation without any permanent damage. Two specific wavelengths are selected: 1064 nm which allows a selective excitation of the laser cavity simulating transient effects of a single particle and 532 nm which interacts with the whole device. The temporal response of the diode is first observed and its shape is interpreted as a function of the physical structure of the device. Then the variation of the time of return to equilibrium after a perturbation is presented as a function of bias current. The limitations on the optical links for both analogue and digital applications are then discussed.
