Embedded photodetectors in polymer waveguides for optical interconnect integrated with a Si-Ge transimpedance amplifier circuit operating at 2.5 Gbit/s

Abstract

In this paper, the first report of a photodetector embedded in a polymer waveguide with output to a Si-Ge transimpedance amplifier is reported. This system was tested with an endfire coupled optical input to the multimode polymer waveguide, and, through direct coupling of this light to the photodetector from the waveguide followed by photodetector current output to a Maxim Si-Ge transimpedance amplifier, operation of this interconnection channel at 2.5 Gbps has been demonstrated.
