Abstract
A radio frequency (RF) photonic spectrometer may include a laser and a receiver branch including an optical modulator optically coupled to the laser and configured to modulate laser light based upon a radio frequency (RF) input signal, and an optical bandpass filter optically coupled to the optical modulator. The spectrometer may further include optical comb branches optically coupled to the laser and each including a frequency comb generator coupled to a respective RF reference signal, with the RF reference signals having different frequencies associated therewith. Furthermore, an output stage may be configured to determine a frequency of the RF input signal based upon outputs of the receiver branch and the optical comb branches.
