The use of two-level atomic systems in quantum optics allows for the design of highly efficient and broadband achromatic retarders through the application of adiabatic passage and composite pulse techniques. In this work, we propose shortcuts to adiabaticity to improve broadband polarization retarders with shorter lengths. We achieve this by inversely engineering the relative refractive indices and further optimizing them with respect to the perturbation of input wavelength. Our results are compared with adiabatic and composite protocols, demonstrating that our method provides the advantage of integrating efficiency and robustness.
量子光学中两级原子系统的应用，通过绝热通道和复合脉冲技术的应用，实现了高效宽带消色差延迟器的设计。在这项工作中，我们提出了绝热捷径，以改进长度更短的宽带偏振延迟器。我们通过逆向设计相对折射率，并针对输入波长的扰动对其进行进一步优化来实现这一目标。我们的结果与绝热协议和复合协议进行了比较，表明我们的方法具有集成效率和鲁棒性的优势。
