The energy consumption of high-speed optical signal processing circuits using optical and electronic components is compared. Integrated nonlinear optical circuits consume more energy than CMOS ICs with O/E and E/O converters in all but the very simplest of circuits. It is concluded that future generations of high-performance electronics will be the technology of choice for optical signal processing. © 2007 The Institution of Engineering and Technology.
