光学相位调制在光通信、信息处理和精密测量等领域具有极其重要的意义。与实空间调制相比，动量空间相位调制具有显著优势：它不受结构中心约束，支持无限的模式容量，并具有固有的拓扑保护。这种固有的灵活性和可扩展性使得实际应用系统无需严格的光学对准即可运行，同时提供大量独立的控制通道，从而推动高性能、高度集成光学系统的发展。光子晶体平板凭借其开放边界周期性和动量空间光场操控能力，已成为动量空间相位场研究的关键平台。基于偏振正交分解和时域耦合模理论中的散射矩阵，本文系统地阐述了光子晶体平板中二维动量空间相位场（包括相位涡旋、相位梯度和相位差）以及多维合成动量空间相位场的产生机制，并回顾了该领域近期研究与应用进展。最后，总结了动量空间相位场领域的发展现状、优势及可能的突破点，并对未来工作进行了展望。
英文摘要
Optical phase modulation is of great significant importance in fields such as optical communication, information processing, and precision measurement. Compared with real-space modulation, momentum-space phase modulation has distinct advantages: it is free from structural center constraints, supports unlimited mode capacity, and possesses intrinsic topological protection. This inherent flexibility and scalability allow practical applications systems to operate without stringent optical alignment while providing a large number of independent control channels, thereby advancing the development of high-performance, highly integrated optical systems. Photonic crystal slabs, with their open boundary periodicity and capabilities for momentum-space optical field manipulation, have become a crucial platform for research on momentum-space phase fields. Based on polarization orthogonal decomposition and the scattering matrix within temporal coupled-mode theory, this paper systematically elucidates the generation mechanisms of both two-dimensional momentum-space phase fields, including phase vortices, phase gradients, and phase difference, and multidimensional synthetic momentum-space phase fields in photonic crystal slabs, and reviews recent research and application progress in this area. Finally, the development status, advantages, and possible breakthroughs in the field of momentum-space phase fields are summarized and prospects for future work are discussed.
