Abstract
An InP-based photoreceiver comprising a waveguide-integrated photodiode and a traveling-wave amplifier is presented, which allows dc-coupled interfacing to subsequent electronics without a bias-T. Getting rid of the bias-T provides cost savings of the receiver operation and improves the available bandwidth, gain, and gain flatness. The redesigned receiver optoelectronic integrated circuit was fully packaged into a pigtailed module with a coaxial 1.85-mm connector. Its optoelectronic conversion capability for nonreturn-to-zero modulated data rates up to 66 Gb/s is shown.
