Researchers at Columbia University have discovered a new way to control the phase of light using 2D materials without changing its amplitude, at extremely low electrical power dissipation. The researchers demonstrated that by simply placing the thin material on top of passive silicon waveguides, they could change the phase of light as strongly as existing silicon phase modulators, but with much lower optical loss and power consumption.
