Keywords:spectral peaking, optical frequency comb, nonlinear polarization rotation

We proposed mode-filtering technique of spectral peaks using nonlinear polarization rotation in optical fiber. Intense, narrow multiple spectral peaks with ~20 dB background ratio were successfully generated with CH₄ gas cell and nonlinear fiber.
