Abstract: A device that includes a multi-segment ring modulator is provided. In particular, the device comprises: an optical waveguide; an optical ring modulator optically coupled to the optical waveguide; a first voltage control device along a first segment of the optical ring modulator; a second voltage control device along a second segment of the optical ring modulator; a first driver device configured to control the first voltage control device to a first voltage and a second voltage; and, a second driver device configured to control the second voltage control device to a third voltage and a fourth voltage. In particular implementations, a ratio of a length of the first segment to a length of the second segment can be one or more of about 2:1 and greater than 1:1, and non-linear driver devices can be used.
