Abstract
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. The ring-shaped waveguide is configured to propagate optical signals having predetermined resonant wavelengths, the electro-optic cladding layer has a voltage-controlled variable refractive index, and the means for applying is configured to apply a wavelength-specific control voltage to the electro-optic cladding layer. The wavelength-specific control voltage will shift or tune the predetermined resonant wavelengths for the ring-shaped waveguide.
