First Claim
Patent Images
1. A modulator apparatus comprising:
- a plurality of optical modulator segments configured to modulate a carrier wave propagating therethrough; and
,a plurality of segment drivers coupled to the plurality of optical modulator segments for driving thereof responsive to an input electrical signal, the plurality of segment drivers configured to drive at least two of the optical modulator segments in accordance with differing limiting voltage transfer functions.

Abstract
An optical modulator apparatus may include a plurality of segment drivers, each segment driver having a unique offset voltage and driving but a portion or a segment of an electro-optical modulator. A modulating electrical signal may be applied to the segment drivers via a plurality of electrical delays. Parameters of the segment drivers may be selected so as to approximate a pre-defined transfer function, which may include a linear or a non-linear transfer function.
