摘要

为了满足多个板载cpu之间在厘米到米尺度上的非阻塞交叉互连的需求，我们提出了基于FR4衬底的聚合物阵列波导光栅路由器（awgr）的设计和制造。所有通道的平均插入损耗为6.28 dB，平均串扰为- 15.77 dB， 3db带宽约为0.8 nm。我们还测试了制备的AWGR的温度稳定性，波长漂移率为-2.23 pm/°C，表明制备的AWGR具有温度不敏感性。

Athermal Polymer Arrayed Waveguide Grating Router for Optical Backplane

To address the demand for non-blocking cross- interconnections between multiple on-board CPUs over centimeter-to-meter scales, we present the design and fabrication of polymer arrayed waveguide grating routers (AWGRs) on FR4 substrates. The measured average insertion loss of all channels is 6.28 dB, while the average crosstalk is −15.77 dB, and the 3-dB bandwidth is approximately 0.8 nm. We also test the temperature stability of the fabricated AWGR, and the wavelength drift rate is -2.23 pm/°C, which reveals the temperature insensitivity of the fabricated AWGR.
