Microwave photonic RF frequency multiplying phase shifter with tunable multiplication factor and a full 360-deg tunable range
摘要
Abstract
A filterless Microwave Photonic Phase Shifter(MPPS)with a tunable Frequency Multiplication Factor(FMF)and a full 360-deg tunable range is theoretically analyzed and verified by simulation.In the scheme,two parallel Mach-Zehnder Modulators(MZM),cascaded with two Dual-Parallel integrated Mach-Zehnder Modulators(DPMZM)by a 2×2 Optical Coupler(OC),are used to generate the±1st-to 4th-order sidebands adjustably,and a Phase Modulator(PM)is used to phase shift one of the two lightwaves.After photodetection,the 2nd-to 8th-order harmonics with a continuously tunable phase shift from 0 to 360-deg can be generated by adjusting the RF driving signal and the DC bias voltage of the DPMZM,and the DC voltage of the PM.Simulation results demonstrate that both 360-deg continuously tunable phase shift and fre-quency multiplication can be implemented.Large Optical Sideband Suppression Ratio(OSSR)and Electric-al Spurious Suppression Ratio(ESSR)of around 20 dB can be obtained.The phase shifter wavelength in-sensitive performance has been also evaluated by simulation.关键词
