Abstract
An optical spectrum generator is disclosed, which is based on generating conjugate optical frequencies via the use of two or more nonlinear interactions, where filters are used to select the conjugate output of the preceding nonlinear interaction as the input to the following nonlinear interaction. The cascaded nonlinear interaction is seeded with an incoming optical beam and pumped with multiple pump beams. The conjugate output of the last nonlinear interaction can be fed-back to the input of the first nonlinear interaction thus creating a recirculating path. An add-drop multiplexer is implemented for efficiently combining the pump beams with conjugate beams. The generated output frequencies are related to the difference in frequency between the pumps which can be changed as a function of time to create a time-varying output frequency. The magnitude of the variation in output frequency can be magnified by recirculating the signal through the system multiple times.
