Serial data conversion redundancy using optical modulators

A system, comprising:

• a look-up table configured to provide an output digital data signal based on selection of a digital data signal or a redundant digital data signal;
• and
• a Mach-Zehnder modulator (MZM) structure that comprises:
• a first waveguide interferometer arm structure that comprises at least a first electrode;
• and
• a second waveguide interferometer arm structure that comprises at least a second electrode,
• wherein the MZM structure is configured to convert an optical input signal into an optical output signal through application of the output digital data signal to the first electrode of the first waveguide interferometer arm structure and the second electrode of the second waveguide interferometer arm structure.
