Computers process information based on arrays of so-called bits. Each bit can take the values of one or zero. This is typically realized with integrated electronic circuits permanently written onto a semiconductor chip.

The word “lens” takes its name from the Latin word for lentil. Both are both hemispheric shapes bound together on their flat surface. So a “flat lens” sounds like a contradiction of terms. Yet that is exactly what Andrei Faraon is working on at California Institute of Technology’s Nanoscale and Quantum Optics Lab.
