You have to fake the wavefront in the VIS wavelenght range,
which asks for phased array optics and
sensors, and a computer to drive them.
All of this is not very difficult with bulk nanoelectronics.
This will work in VIS, but it will be impossible to sustainably prevent a
huge emission in far IR.
Can you dissipate the power anisotropically, anyone knows?
