Abstract: Structures (10) for an optical switch and methods of forming such structures. The structure (10) comprises a first waveguide core (14) including a first portion and a second portion, a second waveguide core (12) including a first portion and a second portion, a ring resonator (18) having a first portion adjacent to the first portion of the first waveguide core (14) and a second portion adjacent to the first portion of the second waveguide core (12), and an optical coupler (20) coupled to the second portion of first waveguide core (14) and the second portion of the second waveguide core (12). The first portion of the ring resonator (18) is spaced from the first portion of the first waveguide core (14) by a first gap over a first light coupling region, and the second portion of the ring resonator (18) is spaced from the first portion of the second waveguide core (12) by a second gap over a second light coupling region.
