Abstract
A method of controlling a polarization scrambler which changes a state of polarization of incident light with time in accordance with a driving voltage. The method includes a first step of applying the driving voltage so that the polarization state of the incident light changes from a starting point and makes N rotations (where N is a positive integer) around a longitude line of the Poincare sphere in a unit time, and a second step of applying the driving voltage so that the polarized light at the starting point on the Poincare sphere becomes the polarized light at an arbitrary position on the Poincare sphere instantaneously. The first step and the second step are repeated.
