80-Gb/s InP-based waveguide-integrated photoreceiver

A waveguide-integrated photoreceiver, comprising a waveguide-integrated photodiode and a distributed amplifier, is presented. Its optical to electrical conversion capability for nonreturn to zero modulated data rates up to 80 Gb/s is demonstrated. The receiver optoelectronic integrated circuit was packaged into a pig-tailed module with a 1 mm connector output.

Design and fabrication of 60-Gb/s InP-based monolithic photoreceiver OEICs and modules

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.

High-sensitivity 40 Gbit/s photoreceiver using GaAsPHEMT distributed amplifiers

The authors report a 40 Gbit/s photoreceiver made with a GaAlInAs/InP 0.78 A/W, a 50 GHz side illumination photodiode and three GaAs PHEMT distributed amplifiers, assembled in a pigtailed module, giving a 37 GHz bandwidth, a 10.4 pA/√Hz average input noise and a 65 dBΩ transimpedance.
