Actually in microprocessors especially, to operate it in G Hz we surely require a optical intervention because of the frequency instability invoved in crystal oscillator or any other at high frequency.In such a case why donot we look for global clock distribution using optical pulses.Optical pulses avoid the cross talk,EMI,skew and many other bugs with electrical counter part.Even recent papers prove that power consumption of receivers with in the chip (to convert the optical to electrical for CMOS circuitry) is less compared to the buffers involved in electrical counterpart.

I am working in the receiver circuitry design and intended to prove that a typical processor if incorporates an optical distribution can perform still better and to the best.

Please share me your comments on this issue.
