Paper Abstract

We present an optical interconnection system that transfers 3- D optical data packets among network nodes using fiber image guides. The fiber image guides (FIGs) are potentially easier to align and package and more flexible in their application than alternative techniques. The testbed system includes a reconfigurable field programmable gate array (FPGA), a transimpedance amplifier (TIA) receiver array, and an optoelectronic very large-scale integrated (OE-VLSI) monolithic smart pixel device. The smart pixel device contains vertical-cavity surface-emitting lasers (VCSELs) and metal - semiconductor-metal (MSM) detectors, and performs optical I/Os for the electronic devices. The TIA receiver chip is used with the MSM detectors to convert photodetected current signals into 5V CMOS compatible signals. These components are mounted on a printed circuit board for testing and evaluation of integrated monolithic OEIC designs. We discuss techniques for butt-coupling the fiber image guides to the VCSEL array and optimizing the coupling distance for VCSEL output. The optical signals are transferred most efficiently through the core fibers in FIGs. When the position of the incident beam is near the center of the cladding the power loss is significant. The system demonstrates high data transmission rates over 16 channels with low crosstalk.
