Optical Interconnects<br />
• Optical interconnects (OIs)<br />
• potential to overcome communication bottleneck<br />
• replace electrical wires with optical waveguides<br />
• OIs offer many advantages over traditional electrical (copperbased)<br />
interconnects<br />
• can support enormous intrinsic data bandwidths in the order of several<br />
Gbps using only simple on–off modulation schemes<br />
• relatively immune to electrical interference due to crosstalk and parasitic<br />
capacitances<br />
• power dissipation completely independent of transmission distance at<br />
the chip level<br />
• routing and placement simplified since it is possible to physically<br />
intersect light beams with minimal crosstalk<br />
• once a path is acquired, transmission latency of the optical data is very<br />
small
