| Abstract: | We have generated a frequency-modulated laser beam by use of cross-phase modulation between orthogonally polarized beams in a polarization-preserving optical fiber. This frequency modulation is based on the temporal intensity beating of the drive beam that is caused by another beam that has a slightly different wavelength. Moreover, we have demonstrated generation of a special frequency-modulated laser beam with temporally changing modulation frequency by use of cross-phase modulation in conjugation with self-phase modulation. |
