Abstract

We present a frequency-selective amplifier for optical frequency combs based on stimulated Brillouin scattering and the effect of a Brillouin dynamic grating. A user defined individual frequency comb line is amplified while the other comb lines are efficiently suppressed, rendering a frequency-stable clean-up oscillator unnecessary. A measured signal to noise ratio of 89dBc/Hz proves the suitability of the method for phase coherent measurements. The overall noise figure is 6 dB.
