Abstract: An optical switching system comprising a switching cell having first and second fixed-position bus waveguides and a moveable shunt waveguide is disclosed. The first bus waveguide includes an input and a first output. The second bus waveguide includes a second output. When the switching cell is in its unswitched state, the shunt waveguide is not optically coupled with either bus waveguide and a light signal can pass from the input to the first output while remaining in the first bus waveguide. When the switching cell is in its switched state, the shunt waveguide is optically coupled with both bus waveguides such that the light signal is coupled out of the first bus waveguide and into the second bus waveguide via the shunt waveguide. As a result, the light signal can pass from the input to the second output while bypassing the first input.
