Abstract: Delay-bandwidth product (DBP) is a key metric in slow light waveguides, requiring a balance between a large group index and broad bandwidth—two parameters that often involve a trade-off. Here, we propose and demonstrate a slow… read more here.

DOI: 10.1103/physrevx.9.031015
Abstract: A new analysis shows how temporal modulation can overcome the size-delay-bandwidth limitation that constrains modern electronic devices, potentially leading to a new wave of ultrasmall high-bandwidth true-time-delay systems. read more here.

DOI: 10.1364/ao.462016
Abstract: We proposed an effective approach to enlarge the slow light bandwidth and normalized-delay-bandwidth product in an optimized moiré lattice-based photonic crystal waveguide that exhibits intrinsic mid-band characteristics. A flatband corresponding to a nearly constant group… read more here.
