EXCERPTS: . . . In Thomas Young’s day, the double-slit experiment involved a relatively simple setup, which included a thin, opaque sheet with two thin perforations oriented side by side, through which light shone onto a detector located behind the sheet. As light enters the slits, it splits into two waves that produce the characteristic interference, either enhancing or canceling each other out and producing a series of bands on the detector, varying in strength based on the amount of light that struck different areas.
Of particular interest to researchers, firing single particles toward the slits still produced the interference pattern, seeming to suggest that the light particle could split into two and travel through both slits at once.
Unlike the “classic” version of the experiment, the Imperial researchers employed their “time slits” to alter the frequency of light passing through indium-tin-oxide, a metamaterial that is also frequently used in smartphone screens. This allowed its color to be changed, rather than just its direction like in Young’s original version, resulting in a similar interference pattern through the manipulation of light coloration.
In the Imperial team’s experiment, the indium-tin-oxide’s reflectance was altered at ultrafast timescales with the use of lasers, which researchers used as the “slits” for the light passing through it, resulting in changes of reflectivity over periods of just a few femtoseconds.
[...] the Imperial team believes the fine control of light through such metamaterial surfaces under conditions similar to those employed in their experiment could have a range of technological applications... (MORE - missing details)
