Electro-optic channel switch

摘要: An optical signal propagated through a poled-polymer input channel waveguide can be switched to selected one of pair output waveguides, while producing only very low cross-talk in the unselected waveguides. The and waveguides are located within non-linear polymer structure so that an end portion is disposed between portions two A first electrodes positioned as apply electric field across second other pairs selectively energized superimpose field-dependent changes upon index refraction either thereby enabling resonantly coupled desired.
