Abstract: A photonic frequency converting transceiver may include a laser, and a downconverter receiver branch including a first optical modulator optically coupled to the laser and configured to modulate laser light based upon an RF input signal and a first optical bandpass filter. An upconverter transmitter branch may include a second optical modulator optically coupled to the laser and configured to modulate laser light based upon an intermediate frequency input signal, and a second optical bandpass filter. A shared local oscillator branch may include a third optical modulator optically coupled to the laser and configured to modulate laser light based upon a local oscillator signal, and a third optical bandpass filter. The transceiver may further include photodetectors optically coupled to the optical bandpass filters to generate a downconverted intermediate frequency output signal and an upconverted RF output signal.

Abstract: A communications device may include a local device, a remote device, and a multi-mode optical fiber coupled between the local device and the remote device. The local device may include a local spatial optical mux/demux coupled to the multi-mode optical fiber and having first and second local optical outputs and first and second local optical inputs, and a local electro-optic E/O modulator coupled to the second local optical input. The remote device may include a remote spatial optical mux/demux coupled to the multi-mode optical fiber, and a remote E/O modulator configured to generate a modulated signal onto a first remote optical output based upon modulating the first optical carrier signal from a first remote optical input responsive to a radio frequency (RF) electrical input signal.
