Abstract
A method produces a wavelength shift into an optical signal. The method includes producing a coherent temporal array of optical signals (CTAS) from an incoming optical signal and broadening the signals of the CTAS to produce a interference pattern. The broadening results from transmitting the CTAS or the incoming optical signal through a dispersive medium. The method also includes selectively transmitting a peak of the interference pattern. The transmitted peak has a selected wavelength shift with respect to the incoming optical signal.
