One embodiment of the present invention is an exemplary wavelength selective optical coupling device. This exemplary device includes two waveguides, a ring or disc resonator, and resonator coupling elements. The waveguides are disposed on top of a substrate, not in contact with each other. The waveguides may transmit multiple wavelengths of light. The ring or disc resonator includes a dielectric member which extends parallel to the top of the substrate and overlaps, without contacting, the waveguides. The resonator is sized to resonate at a subset of resonant wavelengths. The resonator coupling elements couple the resonator to the substrate. The resonator coupling elements may include a bridge coupled to the top surface of the substrate and electrically coupled to control circuitry within the substrate. A waveguide coupling signal from the control circuitry causes the bridge to deform, translating the resonator up and down, thereby intermittently coupling and decoupling the waveguides.
