Abstract

In this paper, we propose the simplest one-dimensional grating waveguide to obtain the wideband slow light. An ideal band indicating group index of 18.3 and bandwidth of 10.3 nm is obtained by plane wave expansion method, which is also verified in the finite-difference time-domain numerical simulation when a Gaussian pulse with bandwidth of 10.3 nm is input into the grating waveguide. Thus, this simple one-dimensional grating waveguide is believed to be widely used as wideband and low loss slow light delay for optical buffering and signal processing.
