Wavelength conversion technique for optical frequency dissemination applications

We demonstrate coherent wavelength conversion capable of covering the entire C-band by modulating the incoming optical carrier with a compact Fabry-Perot cavity embedded phase modulator and by optical injection locking a semiconductor laser to a tone of the generated optical frequency comb. The phase noise of the converted optical carrier over 1 THz frequency interval is measured to be -40 dBc/Hz at 10 Hz offset and the frequency stability is better than 2 x 10(-17) level for averaging times > 1000 s, making this technique a promising solution for comparisons of state-of-the-art optical clocks over complex fiber networks.
