Optical modulators vary the amplitude and phase of a light beam; e.g., from a laser or by sound waves. In optical modulation, not only is the phase and amplitude of a beam of light changed, but optical modulators such as a fiber modulator can alter the frequency and direction of the light beam as well. |
