光子灯笼（PL）是一种锥形波导，可以有效地将光耦合到多根单模光纤中。目前正在考虑将这种装置用于一些任务，包括望远镜和高分辨率光纤光谱仪的耦合、相干检测、调零干涉测量和涡旋光纤调零（VFN）。结合这些用例，PL可以同时执行低阶焦平面波前感测。在这项工作中，我们提供了一个数学框架的光子灯笼波前传感器（PLWFS）的分析，推导线性和高阶重建模型以及度量，通过该传感性能-无论是在线性和非线性制度-可以量化。该框架可以扩展到考虑额外的光学器件，如光束整形光学器件和涡旋掩模，并且可推广到其他波前传感架构。最后，我们提供了初步的数值验证我们的数学模型，通过模拟一个6端口PLWFS。在配套文件中，我们提供了一个更全面的数值表征少端口PLWFSs，并考虑如何控制和优化这些设备的传感性能。
The photonic lantern (PL) is a tapered waveguide that can efficiently couple light into multiple single-mode optical fibers. Such devices are currently being considered for a number of tasks, including the coupling of telescopes and high-resolution, fiber-fed spectrometers, coherent detection, nulling interferometry, and vortex-fiber nulling (VFN). In conjunction with these use cases, PLs can simultaneously perform low-order focal-plane wavefront sensing. In this work, we provide a mathematical framework for the analysis of the photonic lantern wavefront sensor (PLWFS), deriving linear and higher-order reconstruction models as well as metrics through which sensing performance -- both in the linear and nonlinear regimes -- can be quantified. This framework can be extended to account for additional optics such as beam-shaping optics and vortex masks, and is generalizable to other wavefront sensing architectures. Lastly, we provide initial numerical verification of our mathematical models, by simulating a 6-port PLWFS. In a companion paper, we provide a more comprehensive numerical characterization of few-port PLWFSs, and consider how the sensing properties of these devices can be controlled and optimized.
