Abstract
Embodiments of the present invention are directed to optoelectronic network switches. In one embodiment, an optoelectronic switch includes a set of roughly parallel input waveguides and a set of roughly parallel output waveguides positioned roughly perpendicular to the input waveguides. Each of the output waveguides crosses the set of input waveguides. The optoelectronic switch includes at least one switch element configured to switch one or more optical signals transmitted on one or more input waveguides onto one or more crossing output waveguides.
