Abstract: Structures for an optical switch and methods of forming such structures. The structure comprises a first waveguide core including a first portion and a second portion, a second waveguide core including a first portion and a second portion, a ring resonator having a first portion adjacent to the first portion of the first waveguide core and a second portion adjacent to the first portion of the second waveguide core, and an optical coupler coupled to the second portion of first waveguide core and the second portion of the second waveguide core. The first portion of the ring resonator is spaced from the first portion of the first waveguide core by a first gap over a first light coupling region, and the second portion of the ring resonator is spaced from the first portion of the second waveguide core by a second gap over a second light coupling region.
