The OFC system is comprised of a common 2-input optical frequency discriminator (OFD). This makes it possible to frequency stabilize two wavelength-distant lasers onto the same optical reference to reduce their frequency fluctuations and to correlate them. Based on this fact, the optical beat frequency between the two stabilized lasers generates a THz or GHz signal that reaches a very low frequency noise level and high frequency stability.
