19. If the group velocity of a light pulse is reduced by a factor of F from the speed of light in vacuum, the phase-shift operation will be a factor of F slower [L. Deng and M. G. Payne, Phys. Rev. Lett. 98, 253902 (2007).].

31. Due to the symmetric configuration of the system, the linear and nonlinear susceptibilities of both the probe and signal fields are almost equal [see Eq. (5)]. Hence, the curves plotted in Fig. 3 are valid for both the probe and signal fields.

35. The lead time is typically about 10% of c. Thus the device transient time can be estimated quite accurately by using the free-space speed of light [K. J. Jiang, L. Deng, E.W. Hagley, and M. G. Payne, Phys. Rev. A 77, 045804 (2008).].
