ENDLESS POLARIZATION STABILIZER

摘要

A polarization stabilizer (1) for generating from an input optical signal of intensity (I) and polarization (A), an output signal having intensity and polarization substantially independent from the polarization (A), comprising: an input (3) for said input signal; a linear polarizer (6), optionally coupled to said input and having an orientation defined by an inherent axis (PP'), for selecting a portion of said input signal having linear polarization parallel to said inherent axis; an optical element (7) operatively coupled to said linear polarizer for converting said selected portion into said output signal having a circular polarization; an output (9) for said output signal; a control circuit (15) that, based on an electric signal related to the intensity of said output signal, controls the orientation of the linear polarizer.
