多模聚合物光波导构成了一种用于板级光学互连的很有前途的技术。然而，由于其固有的高度多模的性质，VCSEL在高速性能方面的持续改进对其支持如此高的数据速率的能力提出了重要的问题。本文对1.4m长的多模螺旋波导的带宽进行了深入的实验研究，结果表明，即使在发射过满的情况下，带宽长度乘积也至少为35 GHz×m。空间输入偏移量没有显著的传输损伤，而在1.4米长的螺旋波导上的无差错(BER<；；10-12)数据传输以25 Gb/S的速度被证明。
Multimode polymer waveguides constitute a promising technology for use in board-level optical interconnects. However, the continuous improvements in high-speed performance of VCSELs raise important questions about their ability to support such high data rates due to their inherent highly multimoded nature. Thorough experimental studies on the bandwidth of a 1.4-m-long multimode spiral waveguide are presented in this letter, indicating a bandwidth-length product of at least 35 GHz×m even in the case of an overfilled launch. No significant transmission impairments are observed for spatial input offsets, while error-free (BER <; 10-12) data transmission over the 1.4-m-long spiral waveguide is demonstrated at 25 Gb/s.
