We show that a chain of eight coupled cavities of a moderate Q factor can form a continuous dispersion band characterized by extremely flat dispersion and a group index of 105 +/- 20 within a 2.6 nm wavelength range. The experimental results are well reproduced by theoretical calculations based on the guided-mode expansion method.
