These cloaks, the researchers realized, could be used to "trap" light – to slow it down, or even stop it, creating what is known as a "trapped rainbow". The trapped rainbow is seen as different wavelengths of light – and so different colours – that are stopped at slightly different radii within the lens. Now, the same team has made thousands of these cloaks – with each cloak being about 30 μm in diameter – that are then laid out together on a gold sheet. Each microlens bends light around itself, effectively hiding the area it contains. The cloak array was built using a commercially available microlens array that was coated with a gold film 30 nm thick. This was placed, gold-side down, onto a gold-coated glass slide and a laser beam was directed into the array to test the performance of the cloaks at different angles.
