A device that looks like a tiny washboard may clean the clocks of current commercial products used to manipulate infrared light.
New research by the Rice University lab
of Qianfan Xu has produced a micron-scale spatial light modulator (SLM)

to run orders of magnitude faster. Unlike other devices in
two-dimensional semiconducting chips, the Rice chips work in
three-dimensional “free space.”
