Broadband-Packaging Technology and High-Speed Operation of Integrated Optical Front-End Module with InP Devices for Over 1 Tb/s/λ Optical Transmission

Abstract

We fabricated ultra-broadband integrated optical front-end module included InP analog multiplexer ICs and Mach-Zehnder modulator. In addition to the ultra-broadband characteristics of those InP devices, we carefully designed the substrate and interconnection of the module for minimizing the loss derived from assembling. As a result, the module revealed broad EO response of 80 GHz. We successfully generated QPSK signal at the speed of 192 GBaud and demonstrated a 1.3 Tb/s/λ optical transmission (168-GBaud PDM PS-64 QAM) with this module.
