A novel design for complete transfer and robust three-waveguide coupler is presented in this paper, which employs shortcut to adiabaticity (STA) based on stimulated Raman adiabatic passage (STIRAP). Most recently, some remarkable papers on STA of STIRAP [Phys. Rev. A 94(6), 063411 (2016) and Nat. Comm. 7, 12479 (2016)] have been proposed in both theoretical and experimental configurations. In this paper, we propose to design a novel three-waveguide coupler by employing STA based on STIRAP, which can achieve much shorter device length and also maintain the robust performance against perturbations on device geometry parameters compared to previous devices. This finding significantly improves the performance and fabrication of integrated optical devices to build up more compactable devices.

通过绝热的捷径，在三波导耦合器中实现完整而稳定的光传输

本文提出了一种新颖的完全传输和鲁棒三波导耦合器设计，它采用了基于受激拉曼绝热通道（STIRAP）的绝热捷径（STA）。最近，有关STIRAP STA的一些杰出论文[Phys。Rev A 94（6），063411（2016）和Nat。通讯 7，12479（2016）]已在理论和实验配置中提出。在本文中，我们建议采用基于STIRAP的STA设计一种新型的三波导耦合器，与以前的器件相比，它可以实现更短的器件长度，并且还可以保持对器件几何参数扰动的鲁棒性能。该发现显着改善了集成光学设备的性能和制造，以构建更紧凑的设备。
