Illustration shows eight micro-ring modulators and optical waveguide. Each micro-ring modulator is tuned to a specific wavelength -- or “color” of light. By using multiple wavelengths, each micro-ring can individually modulate the light to enable independent communication. This method of using multiple wavelengths is called wavelength-division multiplexing. Credit: Intel Corporation.
