Abstract
An apparatus for shifting the frequency of light comprises a modulator comprising one or more light-reflective elements. The elements are arranged in N groups that are interleaved along the surface of the modulator. The elements are deflected in time in a periodic sawtooth or sinusoidal N-phase manner. The frequency shift can be varied continuously and quickly. Such a modulator may be operated at zero frequency shift, to produce an optical phase shift.
