We propose and analyze a new analog optical link which we refer to as the heterodyne interferometric phase modulated (HIPM) link. The HIPM link phase modulation uses a novel three leg external modulator, has high linearity and suppresses laser relative intensity noise. The link increases the spurious-free dynamic range by 21 dB as compared to a conventional externally modulated AM link for 10 mW of received optical power, relative intensity noise of -130 dB/Hz, and a 15 GHz intermediate frequency.
