Funny, I was wondering the same thing and asked LWLG/MZ Group. They responded that as a matter of policy they do not comment on other companies' technology. Understandable - oh well.
This makes me chuckle too and perhaps someone should update the WIKI for EO modulators, as ours can operate at sub 1 volt levels. It would seem the tables have turned regarding the statement below:
"Compared with an Electro-optic modulator (EOM), an EAM can operate with much lower voltages (a few volts instead of ten volts or more)."
