Abstract
We demonstrate ultrafast, high throughput, all-optical switching in op timized, 2-cm-long, half- and full-beat-length nonlinear directional c ouplers operated at 1.55 mum, below half the band gap of Ga0.82Al0.18A s. The long device length allowed the elimination of nonlinear loss an d resulted in a switching peak power and energy of 85 W and 65 pJ, res pectively.
