Additive manufacturing, also called three-dimensional (3D) printing, has become a robust production technology with many advantages over conventional fabrication techniques, including lower energy and material requirements.

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.
