Abstract
The geometry of photonic crystal waveguides with ring-shaped holes is
optimized to minimize dispersion in the slow light regime. We found geometries
with a nearly constant group index in excess of 20 over a wavelength range of
8 nm. The origin of the low dispersion is related to the widening of the
propagating mode close to the lower band gap edge.
