Ultrafast all-optical switching in GaAlAs directional couplers at 1.55 μm without multiphoton absorption

Year: 1993

Type: article

Abstract: We demonstrate ultrafast, high throughput, all-optical switching in optimized, 2-cm-long, half- and full-beat-length nonlinear directional couplers operated at 1.55 μm, below half the band gap of Ga0.82Al0.18As. The long device length allowed the elimination of nonlinear loss and resulted in a switching peak power and energy of 85 W and 65 pJ, respectively.
