A matrix method for calculating the effective refractive index of guided modes on multilayer dielectric waveguides is developed and employed to calculate the effective electro-optic coefficient of such waveguide structures when one of the media composing them is electro-optic. In properly specified three-layer waveguides, enhancement of the effective electro-optic coefficient above the bulk value by as much as a factor equal to the square of the highest refractive index in the structure is possible. The maximum modulation enhancement for the three-layer guide is attainable with loosely, as well as with tightly, confined waveguide modes.
