Abstract

Previously we have published results on a number of ultrafast high throughput alloptical switching devices in GaAlAs waveguide geometries, at photon energies below half the band gap.^1,2 Here we present experimental results of an integrated alloptical switch based on the zero-gap nonlinear directional coupler and Y-junction (zero-gap NLDC) below half the band gap of GaAlAs semiconductors (at 1.55 µm spectral region).
