WebHoje · 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 the wavevector along the waveguide. Moreover, (3) v g = v p + k d v p d k = v p − λ d v p d λ = c n (1 + λ n d n d λ), where v p is the phase velocity of light, and n g is the group index. Webproposed waveguide is different from the free space wave constant. Needless to mention that for a PCE parallel plate waveguide, the fundamental mode is TEM propagating with 0.
