AI 中文摘要
星间自由空间光链路上的信息与能量联合传输通常基于显式资源分配，这耦合了通信可靠性与能量传递。本文提出一种恒定总功率的斯托克斯正交架构，通过偏振传递信息，同时保留接收光功率用于光伏转换。互补偏振分支通过其交流分量支持平衡信息检测，而其直流分量驱动匹配的多结光子功率转换器。所开发的框架联合表征了指向损伤、误码率、中断和非线性采集功率。分析表明，两个信息符号仅交换分支功率，保持无序输入功率对不变。因此，即使在非线性转换下，总采集能量也保持符号不变，无需显式的信息能量功率分配或线性效率近似。数值结果验证了分析模型，在所考察的指向条件下，闭式误码率近似与精确评估的偏差保持在0.43%以内。与理想无损耗功率分配相比，所提架构避免了传统的误码率与采集功率权衡，并为星间光链路中功率中性的联合信息与能量传输提供了分析基线。
英文摘要
Joint information and energy transfer over inter satellite free space optical links is commonly based on explicit resource splitting, which couples communication reliability and energy delivery. This paper proposes a constant total power Stokes orthogonal architecture that conveys information through polarization while preserving the received optical power for photovoltaic conversion. Complementary polarization branches support balanced information detection through their AC components, while their DC components drive matched multi junction photonic power converters. The developed framework jointly characterizes pointing impaired propagation, bit error rate, outage, and nonlinear harvested power. The analysis establishes that the two information symbols only exchange the branch powers, leaving the unordered input power pair unchanged. Hence, the total harvested energy remains symbol invariant even under nonlinear conversion, without an explicit information energy power split or linear efficiency approximation. Numerical results confirm the analytical model, with the closed form BER approximation remaining within 0.43 percent of the exact evaluation over the examined pointing conditions. Compared with ideal lossless power splitting, the proposed architecture avoids the conventional BER versus harvested power tradeoff and provides an analytical baseline for power neutral joint information and energy transfer in inter satellite optical links.
