Abstract
Devices to mitigate polarization mode dispersion are provided. An example device comprises: an input coupler configured to receive an optical signal comprising a first portion in a first polarization mode and a second portion in a second polarization mode, the second polarization mode about perpendicular to the first polarization mode; an output and/or an optical detector; and one or more optical components configured to convey the optical signal from the input coupler to the output and/or optical detector, one or more of the input coupler and the optical component(s) introducing a total differential group delay between the first and second portions. The optical component(s) comprising: a rotating component configured to rotate the first polarization mode of the first portion to the second polarization mode and rotate the second polarization mode of the second portion to the first polarization mode, to adjust the total differential group delay.
