The multi-wavelength phase stabilization system employs a broadband light source producing a continuous range of wavelengths that include the plurality of discrete optical wavelengths corresponding to the wavelengths to be stabilized. An interferometric mixing system receives the broadband light and the wavelengths to be stabilized, producing a plurality of interference patterns associated with the discrete optical wavelengths. A detecting system produces plural electrical signals based on the intensity of the interference patterns and feeds a control system which produces phase lock-in control signals based on feedback from the electrical signals. A phase shifting system driven by the control system independently adjusts each of the plural discrete optical signals to a stabilized phase, such that the plural discrete optical signals are phase-stabilized to a common reference point.
