MODULATION SYSTEMS USING DUAL CHANNEL OPTICAL MODULATORS |
摘要 |
An optical modulation system for externally modulating two independent optical signals with first, second, third and fourth electrical input signals with two modulators. The system includes a first modulator with a first electrode receiving the first electrical input signal, a second electrode receiving the second electrical input signal, a first optical signal path co-propagating the first optical input signal with the first electrical signal and counter-propagating the second optical input signal to generate a first modulated optical signal, and a second optical signal path co-propagating the second optical input signal with the second electrical input signal and counter-propagating the first optical input signal to generate a second modulated optical signal. The second modulator includes a third electrode receiving the third electrical input signal, a fourth electrode receiving the fourth electrical input signal, a third optical signal path co-propagating the first optical input signal with the third electrical input signal and counter-propagating the second optical input signal to generate a third modulated optical signal, and a fourth optical signal path co-propagating the second optical input signal with the fourth electrical input signal and counter-propagating the first optical input signal to generate a fourth modulated optical signal. |
