第一个观察报告的超快全光开关在一个集成的非对称马赫-曾德尔干涉仪，使用非共振非线性Ga0.82Al0.18As低于一半的带隙。使用耦合腔锁模色心激光器产生的约1.55 μ m的330 fs脉冲，实现了80%以上的相对开关分数。
The first observation is reported of ultrafast all-optical switching in an integrated asymmetric Mach-Zehnder interferometer, using the nonresonant nonlinearity in Ga0.82Al0.18As below half the bandgap. A relative switching fraction of more than 80% has been achieved using 330 fs pulses at around 1.55-mu-m from a coupled-cavity mode-locked colour centre laser.
