WebApr 14, 2024 · The group velocity of light is defined by v g = c/n g, where n g is the group index. Slotted slow light waveguides have already been proven to exhibit small group velocities down to v g = 0.02c [13], [14]. The group velocity v g of light with frequency ω in an optical waveguide is given as: (2) v g = d z d t = Δ ω Δ k = d ω d k, where k is ...
