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.
