Abstract

This paper presents a novel ATM router based on free space optical interconnects. The system consists of a VCSEL/CMOS chip that broadcasts N light beams (channels) which are divided into to M sections. A diffractive optic element then expands the number of these beams into N²/M beams which are incident on a smart photodetector array. This array performs an optical to electronic conversion and selects one of the 'input' channels and routes it to the proper output.
