166 Gb/s PDM-NRZ-DPSK modulation using thin-LiNb03-substrate modulator


The modulation of a 166-Gb/s PDM-NRZ-DPSK signal is demonstrated using a thin-LiNbO3-substrate modulator. The use of a 0.1-mm-thick substrate and a ridge-type waveguide improves the optical response and brings about a reduction in Vπ.
