Abstract

A method includes propagating light in a first waveguide of a 1×2 optical switch. The first waveguide is adjacent to a second waveguide in a coupling region. The 1×2 optical switch comprising an input to receive the light and couple the light to the first waveguide. The 1×2 optical switch further comprising a first output to output light from the first waveguide and a second output to output the light from the second waveguide. The method further includes coupling the light to the first output and the second output based on absorption values of the second waveguide in the coupling region; adjusting absorption values of the second waveguide in the coupling region such that light is directed from the input to only the first output; and coupling light to only the first output based on the adjusted absorption values of the second waveguide in the coupling region.
