An anonymous reader writes "Researchers at [0]Cornell University have
[1]demonstrated a device that allows one low-powered beam of light to
switch another on and off, on silicon, a key component for future
?photonic? microcircuits in which light replaces electrons for
propagating signals. It is highly desirable to use silicon?the dominant
material in the microelectronic industry?as the platform for these
photonic chips. The approach developed confines the beam to be switched
in a circular resonator, greatly reducing the footprint required on the
chip and allowing a very small change in refractive index to shift the
material from transparent to opaque."
