Patent number: 7961988Abstract: A system and method are disclosed for a rapidly tunable wavelength selective ring resonator. An embodiment of a voltage-tunable wavelength selective ring resonator includes a ring-shaped waveguide formed on a semiconductor substrate, an electro-optic cladding layer formed over the ring-shaped waveguide, and voltage applying means for applying a voltage across the electro-optic cladding layer.
