3 Disadvantages of Electrical Interconnects
Scaling Problem —— ”Aspect Ratio” Limit However, optical interconnects do not have such problem!

4 Other Advantages of Optical Interconnects
Timing Accuracy Design Simplification voltage isolation Absence of wave reflection and impedance matching avoid inductive crosstalk frequency independence

5 On-chip Optical Interconnect Data Path
Silicon Optical Modulator Si-based Photo Detector Silicon Laser Silicon Waveguide Driver Amplifier Electrical Logic Cell Electrical Logic Cell

6 Simulated Raman Scattering (SRS)
Si-based Light Source ——Raman Silicon Laser Simulated Raman Scattering (SRS) A reversely biased p-i-n diode to eliminate the TPA-induced FCA

7 Silicon Optical Modulator
metal-oxide-semiconductor (MOS) capacitor Mach-Zehnder Interferometer (MZI)

8 Si-based Photo detector
SiGe multiple quantum wells (MQW)

9 Conclusion The concept of optical interconnect brings a brilliant future for the dense interconnects to the silicon chips. The recent achievement in Intel of the silicon laser, silicon optical modulator and silicon-based photodetector shows the potential of monolithic integration of silicon-based optoelectronics.
