Abstract
Lithium niobate waveguides for light and lithium niobate channel waveguide electro-optic phase modulators for light include sufficient lithium ions such that, when an electrical signal of known value is applied to such waveguides and modulators, the phase of light passing through the waveguide or the modulator changes to a desired value within a time period that is substantially instantaneous.
