Abstract
A Mach-Zehnder interferometer-type modulator for externally modulating two independent optical signals with first and second electrical signals, the modulator includes a first electrode receiving the first electrical signal, a second electrode receiving the second electrical signal, a first optical signal path co-propagating the first optical signal with the first electrical signal and counter-propagating the first optical signal with the second electrical signal, to generate a first modulated optical signal corresponding to the first optical signal modulated with the first electrical signal, and a second optical signal path co-propagating the second optical signal with the second electrical signal and counter-propagating the second optical signal with the second electrical signal, to generate a second modulated optical signal corresponding to the second optical signal modulated with the second electrical signal.
