The authors develop an optical-fiber modulator using magnetic fluid as a cladding layer in this work. By applying magnetic fields, the authors reduced the optical-fiber modulator transmission. Experimental results show that the magnetically induced transmission loss of an optical-fiber modulator under external magnetic fields is dominated by the number of magnetic clusters in the cladding magnetic fluid. Furthermore, it was observed that the formation of magnetic clusters depends on the length of the fiber modulator. In this work, the authors also develop a theoretical model to clarify the transmission characterization of magnetic-fluid optical-fiber modulators.

    A kind of fiber-optic modulation-depth-tunable modulator is developed in this paper. In this modulator, a magnetic fluid is used as the cladding of the drawn fiber, which attenuates the evanescent field when the light is guided in the fiber. Because the attenuation depends on the strength of the...

    The temporal Talbot effect and soliton propagation in an optical fiber were exploited to yield a series of pulse train sources with tunable repetition rate simply through variation of the pulse train power in sections of the fiber. In a dual-repetition-rate configuration, 10 and 20 GHz or 10 and...
