Abstract :
A waveguide crossing optical switch using the depletion edge translation concept is described. By using a single AlGaAs/GaAs material growth and ion implantation technology, an impedance discontinuity is formed at the intersection of two waveguides. Switching operation has been observed, and a high-speed, small-device-size, and high-extinction-ratio optical switch are expected.<>
