Abstract
We use a single-defect photonic crystal waveguide with ring-shaped holes to achieve a small group velocity with relatively low group velocity dispersion.
We show theoretically that a group index larger than 20 with a nearly constant group velocity dispersion parameter of 4.2 ps nm−1 mm−1 over a wavelength range of 5 nm can be achieved. We manufactured a photonic crystal waveguide with ring-shaped holes onto silicon-on-insulator substrate.
From the Fabry–Pérot oscillations in the transmission spectrum, we deduced the group index in the waveguides as a function of the wavelength.
We recorded group index values as large as 22.
