Phased-Array Optics
- peter_d_sherman 6y ago>"Phased-array optics is the technology of controlling the phase and amplitude of light waves transmitting, reflecting, or captured (received) by a two-dimensional surface using adjustable surface elements. An optical phased array (OPA) is the optical analog of a radio wave phased array.[1] By dynamically controlling the optical properties of a surface on a microscopic scale, it is possible to steer the direction of light beams (in an OPA transmitter[2]), or the view direction of sensors (in an OPA receiver[3]), without any moving parts." My curiousity is this: Could an Optical Phased Array be used one day to do the equivalent of Electron Beam Lithography (https://en.wikipedia.org/wiki/Electron-beam_lithography https://en.wikipedia.org/wiki/Electron-beam_lithography) -- but with light -- or could the optical phase array be modified to output electrons, and then could it be used for lithography? ? Maybe today's answer is no... but I think the answer might be "yes", eventually, given enough iterations of research and experimentation...
