In this paper, all-optical modulation of four signal pulses with the interval of 1 ps or 0.67 ps is presented by utilizing GaN-ISBT in a ridge waveguide. The optical pulses are generated by an optical parametric oscillator (OPO) excited by a mode-locked Ti:sapphire laser. The results confirms the possibility all-optical devices operating at a bit rate of 1 Tb/s or higher.
