Photons Trapped by Trick of the Light

The loops act as optical buffers, delaying light by 0.5 nanoseconds before allowing it to continue on its way.

Jeff Hecht writes on NewScientistTech:

Optical microchips that can store light for short periods of time before sending it on its way have been constructed for the first time by researchers at IBM in the US.

The work is an important breakthrough for chip designers who hope one day to use “optical buffers” in superfast processors that rely on photons instead of electrons for their processing power.
