Abstract
An optical fiber polarization scrambler decreasing the degree of polarization (DOP) of light efficiently using at least two optical fiber birefringence modulators (,) and an operating parameter input method for the same. Birefringence modulators are constructed with hollow cylindrical piezo devices (,) and a strand of optical fiber (,) wound continuously on the outer walls of the piezo devices (,). An angle between the birefringence modulators consisting of the optical fiber polarization scrambler is configured to compensate the effect of circular birefringence. A method for exactly configuring birefringence modulation frequency and birefringence modulation amplitude to achieve effective polarization scrambling for the optical fiber polarization scrambler is also provided.
