Abstract
A method of clocking integrated circuit chips. A pulsed laser striking an integrated circuit module substrate is diffused through the substrate and exits the opposite surface as diffused light pulses. An integrated circuit chip mounted on the top surface of the substrate has optical receivers. The optical receivers receive pulsed energy from the diffused light pulses, converting pulsed light to electrical pulses that clock the chip.
