Abstract
A method and system for generating an optical frequency comb that employs a dual parallel modulator that inputs an optical signal at a center frequency of a desired optical frequency comb and an RF signal at a frequency corresponding to a desired spacing of the teeth of the optical frequency comb. The amplitudes of the teeth of the optical frequency comb are controlled by controlling the amplitudes of the two RF inputs to the DPM and the phase shift between the two RF inputs. In some embodiments, the three bias voltages for the three interferometers in the DPM are also controlled. In some embodiments, all three interferometers are all biased at the same point (e.g., quadrature). Preferably, but not necessarily, the three interferometers of the DPM are formed on a single substrate.
