We consider a simple configuration for realizing one-dimensional slow-light metamaterials with large bandwidth-delay products using stub-shaped Fabry-Perot resonators as building blocks. Each meta-atom gives rise to large group indices because of a classical analog of the dressed-state picture of electromagnetically induced transparency. By connecting up to eight meta-atoms, we find bandwidth-delay products over unity and group indices approaching 100. Our approach is quite general and can be applied to any type of Fabry-Perot resonators and tuned to different operating wavelengths. (C) 2015 Optical Society of America
