ABSTRACT:
A tunable optical filter having a number cascaded resonator cavities with each cavity having electro-optic material in its interior. The resonator cavities will resonate at a select wavelength when the index of refraction of the electro-optic material is changed to a predetermined value in response to only a single control voltage. The index of refraction of the electro-optic material is adjusted to a predetermined value by application of the single control voltage to one of a pair of electrodes which are on opposite sides of the resonator cavities.
