A multi-tone high efficient bandwidth system with an eliminated even-order distortions using double dual-parallel Mach-Zehnder modulator

In this paper, a linearization of dual RF channels over single carrier wavelength is proposed and experimentally demonstrated. Multiple microwave signals with multi-octave bandwidth are modulated by double dual-parallel Mach-Zehnder modulator (D-DPMZM) recovered differential balanced detector (BPD). The theoretical experimental model illustrates the elimination second-order harmonic distortions (SHD) intermodulation (IMD2), significant suppression third-order (IMD3) controlling phase input signal DPMZM. photonic link configuration modulation two on optical wavelength, each channel tested for Two-tone to illustrate channelized analog (CAPL). Firstly, mathematical presented even-order using only single-tone in channel. Secondly, purity system mathematically investigated introducing two-tones We have analyzed both test cases, two-tone test, help us understand compare performance system. For case 1 2 our configuration, we achieved fundamental signal-to-interference ratio (S/I) 60 dB 65 spurious-free dynamic range (SFDR) 110 dB.Hz2/3 116 dB.Hz2/3, respectively.
