Abstract
A communications device includes a transmitter device having an optical source to generate an optical carrier signal, and a first modulator coupled to the optical source and to modulate the optical carrier signal with a radio frequency (RF) input signal, and an optical waveguide coupled to the transmitter device. The communications device includes a receiver device coupled to the optical waveguide and including a second modulator to further modulate the modulated optical carrier signal with a local oscillator (LO) signal, a frequency modulation-phase modulation (FM-PM) discriminator coupled to the second modulator and to convert the modulated optical carrier signal to an intensity modulated optical carrier signal based upon the LO signal, and an optical-to-electrical converter coupled to the FM-PM discriminator and to generate an intermediate frequency (IF) signal based upon the intensity modulated optical carrier signal.
