Abstract
The disclosed technique enables fully integrated monolithic hybrid optoelectronic chips to be built that combine electronic circuits, optical devices that are either flip-chip bonded or surface mounted on the VLSI circuits, and fibers. Disclosed is a technique for attaching a fiber optic pigtail to connect a silicon photodetector and a CMOS receiver (or a phototransmitter and a driver) to create a fully integrated CMOS receiver circuit for multimode fiber applications, such as those at a wavelength of about 850 nm. The integrated silicon detector/CMOS receiver can serve as a cheap power/signal monitor (for low speed applications) or even a high-speed Gigabit/s detector.
