| titleOfInvention | Apparatus for measuring state of polarization of a lightwave |
| abstract | Apparatus for measuring state of polarization of an input light beam comprises a linear polarizing element ( 10 ), e.g. a Glan-Taylor prism, an input fiber and lens ( 22,24 ) for directing the input light beam to the linear polarizing element ( 10 ), an output stage ( 26 A- 26 D, 30 A- 30 D, 32 A- 32 D, 34 ) for receiving the light beam leaving the polarizing element, and at least two waveplates ( 12 A, 12 B; 12 B, 12 C) disposed adjacent each other between the input fiber/lens and the linear polarizing element. Each waveplate has its fast axis oriented at a different predetermined azimuthal angle with respect to the incident light beam. The arrangement is such that first and second portions of the input light beam pass through the linear polarizing element and the two waveplates, respectively, and a third portion of the light beam passes through the linear polarizing element without passing through a waveplate. The output stage determines power levels of the three portions of the light beam, respectively, and derives the state of polarization therefrom. |
