AbstractA new approach to generate high-quality optical frequency comb (OFC) with good flatness, high bandwidth, and tunable frequency spacing is proposed. The OFC generator includes a polarization modulator and an intensity modulator (IMS), and the polarization modulator is modulated by a radio frequency multiplication circuit. The theoretical analysis model of the proposed scheme is established. The experiment stimulation results show that 35-line OFC with tunable frequency spacing and spectrum flatness of 0.3 dB and side-mode suppression ratio of 15.53 dB is gotten easily by adjusting the amplitude and frequency of the RF and the direct current bias voltage of the modulators. The stimulation results are in good agreement with the theoretical model.

Recirculation Frequency

AbstractWe propose and experimentally demonstrate a novel scheme to generate a flat and stable optical frequency comb by using recirculation frequency shifter (RFS) loop and polarization-modulator based single-side-band modulator (PSSBM). An ultra-flat 5-carriers generated by a polarization modulator is set as the seed light source of the recirculating loop, and the recirculation times is greatly reduced compared with the regular scheme based on RFS. Through theoretical analysis and experiment simulations, it is shown that the optical frequency comb of high quality with 50 spectral lines and the flatness fluctuation of less than 1 dB can be achieved.
