Webthe observed Kerr efﬁciency of the quartz and SFL-6, respec-tively. The Kerr efﬁciency follows a xth power law of the gate intensity as shown by the broken lines; the value of x for the quartz is 2.4 and that for the SFL-6 is 2.0. For the same gate intensity, the Kerr efﬁciency of the SFL-6 is 60–80 times larger than that of the quartz. WebThe gate is much smaller than similar AND gates based on Bragg gratings and has lower power requirements. We numerically demonstrate the feasibility of constructing an all …
