Harry Potter’s invisibility cloak is one step closer!
American researchers from Towson University and University of Maryland have created and array of 25 000 individual cloaks. This array is the first of its kind. The results were published on the 25th of May in the Institute of Physics and German Physical Society’s New Journal of Physics [1].
In our array, light is stopped at the boundary of each of the cloaks, meaning we observe the trapped rainbow at the edge of each cloak. This means we could do ‘spectroscopy on-a-chip’ and examine fluorescence at thousands of points all in one go.
