Radio frequency polarization modulation based on an optical frequency comb [PDF]

open access: yesRev. Sci. Instr. 91, 083111 (2020);, 2020
We propose a method to generate stabilized radio-frequency polarization modulation based on optical frequency combs. Two pulse trains with the same repetition rate and different offset frequencies generate arbitrary polarization states that are modulated at the offset frequency difference.
