| Abstract(in English) | We experimentally demonstrate ultrafast, low-energy and high-repetition operation of a symmetric Mach-Zehnder (SMZ) all-optical switch. We show that full-switching is possible with a control pulse energy of less than 7 pJ per nonlinear waveguide. We obtain the cross-correlation traces with a full width at half maximum of 2 ps, corresponding to the switching time of l.5 ps. From an analysis of the traces, the switching speed is only limited by the duration of the control pulse. Consequently, the switching speed of the SMZ all-optical switch is not restricted by the slow relaxation of the utilized high-efficiency band-filling effect. Moreover, we show clear switching with a series of four control pulses at intervals of 1{X) or 25 ps. Thus, the repetition rate is also unrestricted by the slow relaxation of the utilized optical nonlinearity. |
