High-speed optical beam-steering based on phase-arrayed waveguides
The authors present a high-speed optical beam-steering system employing phase-arrayed waveguides. They demonstrate a 100 mrad deflection angle at the fastest ever reported instrument-limited deflection speed of 18 GHz and power consumption of 1.8 mW.
