"In 2005, Griffin showed that an InP phase-shift-keying/duobinary Mach-Zehnder interferometer (MZI) modulator could achieve good transmission performance at 10 Gb/s, despite modest residual amplitude modulation in the phase modulators in the MZI (ratio of real to imaginary part of index change was similar to 0.1)," researchers in the United States report.
"Here we show that even strong amplitude modulation in the ''phase'' modulators (ratio of real to imaginary part of index change is similar to 1.0) gives good transmission performance. Allowing for strong amplitude modulation allows a significant increase in modulator bandwidth," wrote C.R. Doerr and ...
