Abstract :
A new heterodyne interferometric phase modulation (HIPM) link and a new subcarrier frequency modulation with direct detection (SFM-DD) link are proposed. To generate angle-modulated signals at the receiver, the HIPM system utilize a novel external modulator, while the SFM-DD system uses electronic preprocessing. The spurious free dynamic ranges (SFDR) of the SFM-DD and HIPM systems are larger than that of the amplitude modulation with direct detection (AMDD) system; when relative intensity noise (RIN) is dominant, these two systems can show 26 dB and 28 dB advantages with respect to the AMDD system, respectively
