摘要

We present a slow light photonic crystal waveguide. In our structure design, we displace some air holes perpendicular to the line defect. By tuning the group index, n(g), from 11.8 to 40, we attain a wide bandwidth varying from 15.9 to 46.9 nm. The group velocity dispersion is kept below 10(-20) m(-1) s(2), and the normalized delay-bandwidth product of 0.448-is attained at n(g) = 14.8 by this structure. This study uses plane wave expansion and finite-difference time domain methods. (C) 2016 Society of Photo-Optical Instrumentation Engineers (SPIE)
