Abstract:
A system may include: an optical pulse source; fiber optic links; a first optical coupler optically coupled to the optical pulse source; a radiofrequency (RF) source; a phase modulator (PM) optically coupled to the first optical coupler and electronically coupled to the RF source; an interleaving delay optically coupled to the first optical coupler; a second optical coupler optically coupled to the PM and the interleaving delay; a laser; an optical amplifier optically coupled to the laser; a wavelength division multiplexer (WDM) optically coupled to the optical amplifier and the optical coupler; a highly nonlinear fiber (HNLF); an optical filter optically coupled to the WDM via the HNLF; an optical switch optically coupled to the optical filter; and a coherent detector optically coupled to the optical switch via a first optical path and a second optical path, the first optical path including an optical delay.
