相干接收器可以解调高速的同相和正交光信号，是光通信、互连、成像和计算的重要组成部分。然而，传统的基于波导基的相干接收机存在占地面积大、难以有效地耦合大量空间信道以及基于波导基的光混合所施加的工作带宽有限等问题。在这里，我们提出了一种表面法线相干接收器，它直接集成在光电探测器上，而不需要光学混合电路。使用具有平行占据70-μm-2的有源部分的制造的器件
A coherent receiver that can demodulate high-speed in-phase and quadrature signals of light is an essential component for optical communication, interconnects, imaging, and computing. Conventional waveguide-based coherent receivers, however, exhibit large footprints, difficulty in coupling a large number of spatial channels efficiently, and limited operating bandwidth imposed by the waveguide-based optical hybrid. Here, we present a surface-normal coherent receiver with nanometallic-grating-based polarizers integrated directly on top of photodetectors without the need for an optical hybrid circuit.
