Abstract
Disclosed are bias control methods for Mach-Zehnder modulators for the generation of optical QAM signals while ensuring correct I/Q polarity of the generated optical QAM signal. One exemplary method involves temporarily offsetting I and Q biases from ideal transmission null bias points while another illustrative method temporarily makes I and Q data streams identical.
