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.

26. A modulator apparatus comprising:
-
a plurality of optical modulator segments sequentially disposed in an optical path of an optical carrier wave and configured to successively modulate the optical carrier wave so as to obtain a modulated optical signal; and
,a plurality of segment drivers individually coupled to the plurality of modulator segments and configured to drive each of the optical modulator segments synchronously with propagation of the optical carrier wave therein in accordance with a limiting voltage transfer function. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
