摘要

在本工作中，我们提出了一种具有超长工作距离和近红外波长复用的计算机生成波导全息图耦合器的设计。提出了一种计算绕行相位全息图标量场的近似方法。精度与FDTD相当，但实现速度要快得多。利用该方法优化了波导到自由空间的耦合效率和设计的制造可行性。

Design of a computer-generated waveguide hologram for integrated free space sensing

In this work we present a design of a computer-generated waveguide hologram coupler with an ultra-long working distance and wavelength multiplexing in the near infrared. An approximation method to compute the scalar field from a detour phase hologram is presented. The accuracy is comparable to FDTD but it is achieved much faster. Coupling efficiency from waveguide to free space and fabrication feasibility of design are optimized with the method.
