ABSTRACT:
A polarization desensitizing method and apparatus including a polarization analyzer separating a polarized input pulse into two orthogonally polarized components separated in time; and a nonlinear switch integrating the power of the two orthogonally polarized components over a predetermined time and producing an output pulse having a predetermined polarization. In one embodiment the polarization desensitizer includes a polarization analyzer in communication with a data source providing data pulses; a pulse generator; and a polarization converting switch in communication with both the polarization analyzer and the pulse generator, the polarization converting switch producing output pulses of a known polarization in response to the data pulses.
