Manipulating multiple lasers on a single chip for a new generation of quantum devices


"combined integrated photonic circuits optical metasurface... glass wafers imprinted with millions of tiny structure few hundred billionths of meter high... single photonic chip did work of 36 optical components, simultaneously controlling direction, focus, and polarization of 12 laser beams divided among four distinct colors... portable sensors measure rotation, acceleration, miniature optical atomic clocks, quantum computers and magnetic fields with unprecedented accuracy"
