Abstract

In contrast to recent reports of localization-impaired transport in long slow-light waveguides, we demonstrate light transport in silicon coupled-resonator optical waveguides (CROWs) consisting of up to 235 coupled microrings without localization over frequency bands that are several hundred gigahertz wide. Furthermore, from the unique statistical signatures provided by time-domain propagation delay measurements, we demonstrate the spectrally correlated nature of light propagation in CROWs.

摘要

与最近关于长慢光波导中传输定位受损的报道相反，我们展示了在由多达235个耦合微环组成的硅耦合谐振器光波导（CROW）中的光传输，其在数百吉赫兹宽的频带上没有出现定位现象。此外，根据时域传播延迟测量提供的独特统计特征，我们证明了CROW中光传播的光谱相关特性。
