Optical interconnect is a means of communication by optical fiber cables. Compared to traditional cables, optical fibers are capable of a much higher bandwidth, from 10 Gbit/s up to 100 Gbit/s. Riding on the achievements of photonic technologies, a wide range of studies have been done.
IBM created a prototype optical interconnect using wavelength-division multiplexing (WDM). They suggest that if successful, this technology could lead to the first computer capable of exascale computing (a computer that can perform a billion billion computations per second). A waveguide emits eight different colored beams into several different ports of a modulator, which allows eight signals to be transferred concurrently. This multi-wavelength beam travels through the chip, with optical switches controlling the direction.
