Abstract
Embodiments of the invention provide apparatuses and methods for generating frequency combs. A non-linear optical medium may generate new optical waves centered at frequencies differing from the input waves, while retaining the input wave properties. In the case when a parametric mixer is used to generate frequency combs with small frequency pitch, the phase correlation of the input (seed) waves can be achieved by an electro-optical modulator and a single master laser. In the case when a frequency comb possessing a frequency pitch that is larger than frequency modulation that can be affected by an electro-optic modulator, the phase correlation of the input (seed) waves is achieved by combined use of an electro-optical modulator and injection locking to a single or multiple slave lasers.
