    Abstract: A communications system may include an optical source to generate an optical carrier signal, and an RF signal path including a first electro-optic (EO) modulator to modulate the optical carrier signal based upon an RF signal, a stimulated Brillouin scattering (SBS) device coupled to the first EO modulator, and an optical circulator downstream from the SBS device. A local oscillator (LO) path may include a second EO modulator coupled to the optical source to modulate the optical carrier signal based upon an LO signal, and an optical bandpass filter(s) coupled to the second EO modulator. A filter function path may be coupled to the optical circulator and include a third EO modulator to perform optical modulation based upon a filter function signal. A detector may be coupled to the RF signal path and the LO path to generate an intermediate frequency (IF) signal.
