ABSTRACT:
An apparatus for transforming a polarization and a method thereof are provided. The apparatus includes a polarization rotator for rotating a polarization plane of an input optical signal by a specified rotating angle, a polarization beam splitter for dividing the polarization of the optical signal output from the polarization rotator into first and second polarization components, a first monitoring unit for monitoring the first polarization component, a second monitoring unit for monitoring the second polarization component, and a controller for controlling a rotating angle of the polarization rotator so that strengths of the optical signals output from the first and second monitoring unit become equal to each other. Accordingly, a desired polarization component having a constant strength can be obtained by controlling only the rotating angle of the polarization rotator.
