A general derivation of the optical modulation process in a dual-drive Mach
-Zehnder modulator (DD-MZM) is introduced. The expressions include all harm
onics and are entirely general in terms of bias point. Chromatic dispersion
is also included allowing the prediction of a number of important phenomen
a in photonic signal transmission. Examples of special cases of these gener
al equations are then presented. Similar expressions are introduced for har
monic optical up-conversion through a photonic mixer based on a DD-MZM cove
ring any bias point or phase shift between DD-MZM drives.
