资源简介：
We demonstrate a PLC-based O-Band 8-channel cascaded AWG design. The manufactured prototypes achieve 400 GHz channel spacing while simultaneously reaching a 1 dB bandwidth of 300 GHz and a crosstalk below -40 dB. The measured fiber-to-fiber loss is as low as 2.7 dB and the PDL is below 0.2 dB. We determine a low thermal drift of \u20111.8 GHz\/Kelvin. The combination of low IL, high bandwidth, low crosstalk, and low thermal drift make the device particularly attractive for WDM-based data center and AI networks architectures that benefit from a large network switch radix.
