Abstract

We find that electromagnetic pulses can be greatly delayed in a two-dimensional (2D) meander-line photonic crystal waveguide, which incorporates a row of perfect electric conductor (PEC) slabs and a magnetooptical photonic crystal under a static magnetic field. The electromagnetic pulse has a one-way property with broken time-reversal symmetry and circumvents the PEC slabs to propagate through the waveguide, leading to the considerable increase of propagation path and nearly three-fold enhancement of group delay compared to the straight waveguide.
