Abstract
We developed flexible printed circuit RF interface InP-based coherent driver modulators with a 3-dB bandwidth of over 80 GHz for 128-Gbaud or higher operations. Low insertion loss (<8.5 dB per polarization), low polarization-dependent loss (<0.1 dB), and high extinction ratio (>30 dB) were achieved.
