Micro Ring Resonator

New measurements provide a glimpse into the quantum future

The micro-ring resonator, shown here as a closed loop, generated high-dimensional photon pairs. The researchers examined these photons by manipulating the phases of different frequencies, or colors, of light and mixing frequencies, as shown by the criss-crossing multicolored lines.
