An optical frequency comb (OFC) generator based on an electro-optic Talbot laser and cross-phase modulation (XPM) in a high nonlinear fiber (HNLF) is designed and demonstrated. The Talbot laser is an electro-optic frequency shifting loop that is used to produce repetition rate-multiplied pulses, and these pulses work as a pump signal that induces the XPM process in the HNLF to modulate the phase of a probe signal. At the output of the HNLF, OFCs with a multiplied line spacing can be generated. The effects of the pump power and the HNLF length on the performance of the generated OFCs are theoretically analyzed. In the experiments, the line spacing of the generated OFCs is multiplied to be 10 GHz, 15 GHz, and 20 GHz with a factor of 2, 3, and 4, respectively. The center of the OFCs is tuned in a 4 nm range by adjusting the wavelength of the probe signal.

“…Various schemes have been proposed for photon-assisted instantaneous frequency measurement, including the microwave photonic instantaneous frequency measurement based on the frequency-topower mapping in microwave photonic links, a photonic channelized receiver based on beat frequency principle, and a photonic scanning receiver based on a tunable F-P etalon [15][16][17]. However, the microwave photonics instantaneous frequency measurement is not suitable for the multi-frequency microwave signal measurement, and the photonic scanning receiver scheme is unable to process the signal quickly due to the limitation of the tuning speed of the lter.…”

“…However, due to the application of the F-P lter, there is a certain range of error in the ltering process, and the frequency measurement range is also limited, which usually cannot meet the accuracy requirement. In [17], microwave multi-frequency measurement based on an optical frequency comb and a photonic channelized receiver is proposed. However, in the lower branch of this scheme, a higher-frequency RF signal is used to drive the modulator to generate ± 1st order sidebands, and then a lter is used to lter out the + 1st order sideband to achieve frequency shift, which improves the requirements of the RF drive signal and the lter.…”

A novel microwave photonic channelized receiver and multi-band frequency conversion system based on optical frequency comb (OFC) is proposed and demonstrated. In the proposed scheme, the RF signal is modulated by a polarization modulator to generate 6-line OFC on the upper branch, and the microwave signal is modulated by the polarization modulator to generate ±st order sidebands on the lower branch. The upper and lower signals are coupled by an optical coupler and channelized by a wavelength division multiplexer to realize instantaneous frequency measurement and multi-band frequency conversion of microwave signals. The result shows that microwave signals from 0GHz to 29GHz can be measured by adjusting the comb spacing to 10GHz. When the microwave signal is 22GHz, the frequency conversion of microwave signal can also be completed by this system after the completion of frequency measurement, and it can be down-converted to 1.98GHz (L band), 8.05GHz (X band), 18.05GHz (K band) and can be up-converted to 28.05GHz (Ka band), 38.05GHz (Ka band), 48.05GHz (U band).
