An array of nanometric optical screws in different screwing directions that allow you to control the light that passes through. On the right - an electron microscope image of the array of optical nanometer screws, on the left - the illumination of the array of screws with light with rotation in different directions: the creation of the word spin in illumination with counterclockwise rotation, and the complementary image for clockwise illumination.

An array of nanometric optical screws in different screwing directions that allow you to control the light that passes through. On the right - electron microscope image of the array of optical nanometer screws, on the left - illumination of the array of screws with light with spin in different directions: creating the word spin in anti-clockwise spin illumination, and the complementary image for clockwise illumination.
